Remove '\\' char from string c#

问题:

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.

回答1:

You could use:

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

or

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

回答2:

You can use String.Replace which basically removes all occurrences

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

回答3:

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

回答4:

Why not simply this?

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

回答5:

Try using

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

回答6:

Try to replace

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

回答7:

to remove all '\' from a string, simply do the following:

myString = myString.Replace("\\", "");

回答8:

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);

         while ((line = stringReader.ReadLine()) != null)
         {
             // split the lines
             for (int c = 0; c < line.Length; c++)
             {
                 line = line.Replace("\\", "");
                 lineBreakOne = line.Substring(1, c - 2);
                 lineBreakTwo = line.Substring(c + 2, line.Length - 2);
             }
         }
