C#中WindowsForm常见控件的运用 --1.button(曹操,贡天子以令不臣): 属性;text:我们经常可以看见将按钮命名为“登入”,在其属性面板里面编辑text即可;如下图:
事件:click是我们常常用到的,点击按钮发生的事件,如,弹出:你好!,在事件面板下click下就可完成,:
其中代码如下:
View Code
1 private void button1_Click(object sender, EventArgs e) 2 { 3 MessageBox.Show("欢迎你!"); 4 }
2.textBox: 其中我们在输入密码的时候会用到一个属性:passworchar,来掩饰密码:
View Code
1 private void groupBox1_Enter(object sender, EventArgs e) 2 { 3 textBox2.PasswordChar='*'; 4 }
2.1,RichTextBox, 3.经过以上的描述我就写个连贯的控件来叙述; 3.1.一个登入面板,要求账号为:lixiaofeng,密码;6080;
3.1.1.进入面板点击登入按钮的代码(其中的验证涉及到验证控件errorprovider): 1 using System; 2 using System.Collections.Generic; 3 using System.ComponentModel; 4 using System.Data; 5 using System.Drawing; 6 using System.Linq; 7 using System.Text; 8 using System.Threading.Tasks; 9 using System.Windows.Forms; 10 11 namespace WindowsFormsApplication1 12 { 13 public partial class Form1 : Form 14 { 15 public Form1() 16 { 17 InitializeComponent(); 18 } 19 20 private void Form1_Load(object sender, EventArgs e) 21 { 22 23 } 24 25 private void button1_Click(object sender, EventArgs e) 26 { 27 28 } 29 30 private void groupBox1_Enter(object sender, EventArgs e) 31 { 32 33 } 34 35 private void button1_Click_1(object sender, EventArgs e) 36 { 37 38 //首先要求账号输入长度大于3,其次密码为int型,所以就要写个验证代码提示,如下: 39 if (textBox1.Text == "") //判断是否为空 40 { errorProvider1.SetError(textBox1, "对不起,这里不能为空!"); } 41 else 42 { 43 try 44 { 45 if (textBox1.Text.Length > 3) 46 { errorProvider1.SetError(textBox1, ""); } 47 else 48 { errorProvider1.SetError(textBox1, "要求要输入3个以上的数据!"); } 49 } 50 catch 51 { errorProvider1.SetError(textBox1,"您的输入有问题,请重新输入!"); } 52 } 53 if (textBox2.Text == "") 54 { errorProvider1.SetError(textBox2, "对不起,这里不能为空!"); } 55 else 56 { 57 try 58 { int i = Int32.Parse(textBox2.Text.Trim()); errorProvider1.SetError(textBox2, ""); } //判断是否输入的是int数字 59 catch 60 { errorProvider1.SetError(textBox2,"这里只能输入数字密码!"); } 61 } 62 63 //满足账号为:lixiaofeng 密码是:6080 即可进入,代码如下: 64 if (textBox1.Text == "lixiaofeng" && Int32.Parse(textBox2.Text.Trim()) == 6080) 65 { Form2 f2 = new Form2(); f2.Show(); } //打开登入后的页面 66 67 this.AcceptButton = button1;//默认按下回车后==点击登入按钮 68 69 } 70 71 private void textBox2_TextChanged(object sender, EventArgs e) 72 { 73 label3.Text = textBox2.Text.Trim(); //密码翻译 74 } 75 } 76 } 4.计算器/添加器; 计算器: 需要的控件有:imagelist/tabcontrol, 在命名,加载图片完成后,要求选择运算功能后记录运算记录: 4.1.选项卡加载图片: 1 private void Form2_Load(object sender, EventArgs e) 2 { 3 //首先添加当前的选项卡图标; 4 tabControl1.ImageList = imageList1; 5 tabPage1.ImageIndex = 0; tabPage2.ImageIndex = 1; 4.2.点击运算后的过程代码: 1 private void button5_Click(object sender, EventArgs e) 2 { 3 double deshu=0; 4 if (textBox2.Text == "") 5 { MessageBox.Show("请输入数据!", "", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); } 6 else 7 { 8 9 if (radioButton1.Checked == true) //选择加法功能 10 { 11 string[] fengejieshou = textBox2.Text.Split('+'); //分割“+”存储 12 for (int i = 0; i < fengejieshou.Length; i++) 13 { deshu += Convert.ToDouble(fengejieshou[i]); } //做加法运算 14 textBox3.Text = deshu.ToString(); //输出结果显示 15 } 16 else //没有选择运算功能就进行提示 17 { MessageBox.Show("请选择运算功能","",MessageBoxButtons.OK,MessageBoxIcon.Asterisk ); } 18 19 } 20 21 //将运算记录写入登记表中去: 22 //设置其滚动条等属性; 23 listBox1.HorizontalScrollbar = true; listBox1.HorizontalScrollbar = true; 24 //设置其编辑属性: 25 listBox1.SelectionMode = SelectionMode.MultiExtended; 26 //写入记录: 27 string xierujilu = string.Format("操作数:{0}\t计算结果是:{1}",textBox2.Text,deshu.ToString()); //整理数据字符串 28 listBox1.Items.Add(xierujilu ); //写入到表中 29 30 } 4.3.添加选项卡/及文本链接功能:
对选项卡的添加/删除/清空代码: 4.4.添加: 1 private void button1_Click(object sender, EventArgs e) 2 { 3 //手动添加选项卡代码的实现: 4 if (textBox1.Text == "") 5 { MessageBox.Show("请输入新选项卡的名字!", "", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); } 6 else 7 { tabControl1.TabPages.Add(textBox1.Text ); //添加新选项卡 8 tabControl1.TabPages[tabControl1.TabCount-1].ImageIndex=2; //向新卡添加图片 9 textBox1.Text = "";//清空输入信息 10 } 4.5.删除: 1 private void button2_Click(object sender, EventArgs e) 2 { 3 //删除选项卡代码: 4 if (tabControl1.SelectedIndex == 0 || tabControl1.SelectedIndex == 1) 5 { MessageBox.Show("这里系统自带的无法删除!", "", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); } 6 else 7 { tabControl1.TabPages.Remove(tabControl1.SelectedTab); } //删除 8 } 4.6.清空:
View Code
4.7.超文本链接: 1 private void tabPage2_Enter(object sender, EventArgs e) 2 { 3 //显示滚动条 4 richTextBox1.ScrollBars = RichTextBoxScrollBars.ForcedBoth; 5 //设置字体: 6 richTextBox1.SelectionFont = new Font("隶书", 12, FontStyle.Bold); 7 //字体颜色; 8 richTextBox1.SelectionColor = System.Drawing.Color.Red; 9 //字体text属性 10 richTextBox1.Text = "欢迎进入我的博客园:http://www.cnblogs.com/liyifeng/"; 11 } 1 private void richTextBox1_LinkClicked(object sender, LinkClickedEventArgs e) 2 { 3 System.Diagnostics.Process.Start(e.LinkText ); //链接文本 4 } 5.资源管理器:
5.1.添加节点,并添加节点图片: 1 public void Form3_Load(object sender, EventArgs e) 2 { 3 //工具和视图,为2个根节点: 4 TreeNode t1 = treeView1.Nodes.Add("工具"); 5 TreeNode t2 = treeView1.Nodes.Add("视图"); 6 //在工具节点中添加2个子节点,和编辑相应的对象: 7 TreeNode t11 = new TreeNode("运算器/选项卡"); TreeNode t12 = new TreeNode("添加视图"); 8 t1.Tag = "1"; t11.Tag = "11"; t12.Tag = "12"; 9 t1.Nodes.Add(t11); t1.Nodes.Add(t12); 10 //在视图中添加3个子节点: 11 TreeNode t21 = new TreeNode("平铺"); TreeNode t22 = new TreeNode("垂直"); TreeNode t23 = new TreeNode("层叠"); 12 t2.Tag = "2"; t21.Tag = "21"; t22.Tag = "22"; t23.Tag = "23"; 13 t2.Nodes.Add(t21); t2.Nodes.Add(t22); t2.Nodes.Add(t23); 14 15 //添加节点的图片: 16 treeView1.ImageList = imageList1; 17 //设置2个根节点的图片: 18 t1.ImageIndex = 1; t1.SelectedImageIndex = 1; t2.ImageIndex = 2; t2.SelectedImageIndex = 2; 19 20 21 } 5.2.编写双击节点后的事件: 1 private void treeView1_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e) 2 { 3 if (treeView1.SelectedNode.Tag == "11") 4 { Form2 f2 = new Form2(); f2.Show(); }//打开运算器页面 5 if (treeView1.SelectedNode.Tag == "12") 6 { Form4 f4 = new Form4(); f4.Show(); } 7 if (treeView1.SelectedNode.Tag == "21") 8 { 9 Form2 f2 = new Form2(); f2.MdiParent = this; Form4 f4 = new Form4(); f4.MdiParent = this; 10 f2.Show(); f4.Show(); 11 LayoutMdi(MdiLayout.TileHorizontal ); 12 } 13 if (treeView1.SelectedNode.Tag == "22") 14 { 15 Form2 f2 = new Form2(); f2.MdiParent = this; Form4 f4 = new Form4(); f4.MdiParent = this; 16 f2.Show(); f4.Show(); 17 LayoutMdi(MdiLayout.TileVertical ); 18 } 19 if (treeView1.SelectedNode.Tag == "23") 20 { 21 Form2 f2 = new Form2(); f2.MdiParent = this; Form4 f4 = new Form4(); f4.MdiParent = this; 22 f2.Show(); f4.Show(); 23 LayoutMdi(MdiLayout.Cascade ); 24 } 25 26 27 } 5.3:运行图示: 6.菜单添加器:
6.1分组及集合的编写: 1 private void Form4_Load(object sender, EventArgs e) 2 { 3 //创建2个分组: 4 listView1.Groups.Add(new ListViewGroup("相片",HorizontalAlignment.Left )); 5 listView1.Groups.Add(new ListViewGroup("其他",HorizontalAlignment.Left )); 6 //创建2个图标集合: 7 listView1.Items.Add("我的书法"); listView1.Items.Add("相片"); 8 //将其添加都分组为:相片组里: 9 listView1.Items[0].Group=listView1.Groups[0];listView1.Items[1].Group=listView1.Groups[0]; 10 11 //将杂集放到,其他里面 12 listView1.Items.Add("杂集"); 13 listView1.Items[2].Group=listView1.Groups[1]; 14 15 //设置视图样式: 16 listView1.View = View.Tile; 17 //向视图中添加图片: 18 listView1.LargeImageList = imageList1; 19 listView1.Items[0].ImageIndex = 0; listView1.Items[1].ImageIndex = 1; listView1.Items[2].ImageIndex = 2; 20 21 22 } 6.2添加/删除/清空,的功能: 1 private void button1_Click(object sender, EventArgs e) 2 { 3 //以下为添加信息的同时添加视图的图片: 4 if (textBox1.Text == "") 5 { MessageBox.Show("请输入要添加的命名"); } 6 else 7 { listView1.Items.Add(textBox1.Text.Trim()); 8 listView1.Items[listView1.Items.Count-1].Group=listView1.Groups[1]; 9 listView1.Items[listView1.Items.Count - 1].ImageIndex = 3; 10 textBox1.Text = ""; 11 } 12 } 13 14 private void button2_Click(object sender, EventArgs e) 15 { 16 listView1.Items.RemoveAt(listView1.SelectedItems[0].Index ); 17 } 18 19 private void button3_Click(object sender, EventArgs e) 20 { 21 listView1.Items.Clear(); 22 } 6.3,进入:管控页面的代码:
