1、新建一个类库解决方案 CommnoLog

2、新建两个文件夹

      2.1FileUtil.cs  代码如下

public static class FileUtil
{
/// <summary>
/// 追加内容到指定文件中
/// </summary>
/// <param name="filePath"></param>
/// <param name="content"></param>
public static void WriteAppend(string filePath, string content)
{
WriteAppend(filePath, new string[] { content });
}

public static void WriteAppend(string filePath, string[] contents)
{
//System.IO.StreamWriter sr = new System.IO.StreamWriter(filePath, true);
//foreach (string c in contents)
//{
// sr.WriteLine(c);
//}
//sr.Flush();
//sr.Close();

using (FileStream fs = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.Write, FileShare.ReadWrite))
{
fs.Seek(fs.Length, SeekOrigin.Current);

string content = String.Join(Environment.NewLine, contents) + Environment.NewLine;

byte[] data = System.Text.Encoding.UTF8.GetBytes(content);

fs.Write(data, 0, data.Length);

fs.Close();
}
}
}

文件夹2、
