trim - Remove '' char from string c#

Question

I have the following code

string line = ""; 

while ((line = stringReader.ReadLine()) != null)
{
    // split the lines
    for (int c = 0; c < line.Length; c++)
    {
        if ( line[c] == ',' && line[c - 1] == '"' && line[c + 1] == '"')
        {
            line.Trim(new char[] {'\'}); // <------
            lineBreakOne = line.Substring(1, c  - 2);
            lineBreakTwo = line.Substring(c + 2, line.Length - 2);
        }
    }
}

I have added a comment net to the line I am wondering about. I want to remove all '' chars from the string. Is this the correct way to to this? I doesnt work. All are still in the string.
