Remove '\' char from string c#

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.

I have faced this issue so many times and I was surprised that many of these don't work.

I simply deserialize the string with Newtonsoft.Json and I get cleartext.

string rough = "\"call 12\"";
rough = JsonConvert.DeserializeObject<string>(rough);

//the result is: "call 12";

Try to replace

string result = line.Replace("\\","");

Trim only removes characters at the beginning and the end of the string, that's why your code doesn't quite work. You should use Replace instead:

line.Replace(@"\", string.Empty);

You can use String.Replace which basically removes all occurrences

line.Replace(@"\", "");

String sNew =     sOld.Replace("\\", String.Empty);

Why not simply this?

resultString = Regex.Replace(subjectString, @"\\", "");

You could use:

line.Replace(@"\", "");

line.Replace(@"\", string.Empty);
