Process "\" in a string to "\\" for FilePath processing [duplicate]

Question

I have a function in where I want to convert a string value C:\samplec#programs\Converter to C:\\samplec#programs\\Converter Note the differences. This is my function:

private string FilePathProcessor(string path)
{
    char[] oriCharArray = path.ToCharArray; 
    List<char> oriCharList = new List<char>;
    List<char> newCharList = new List<char>;
    foreach (char item in oriCharArray)
    {
        oriCharList.Add(item);
    }

    foreach (char items in oriCharList)
    {
        if ((items != "\\"))
        {
            newCharList.Add(items);
        }
        else
        {
            newCharList.Add(items);
            newCharList.Add(items);
        }
    }

    string result = string.Join(",", newCharList.ToArray());
    return result;
}

Of course this function serves my needs. But, I wonder if there is already an existing function in .Net which will take care of it. I am just cleaning up my code and checking for simpler and faster solution. Not going to reinvent the wheel if there is already a way.

Actually, I am placing this value into a mysql database. When I write it in the original form, it misses the "\". I have some hundreds of thousands of these values need to be processed before I could place it into my database table — Hari

Have you tried using SomeTypeOfWriteMethod(@"C:\sample#programs\Convertor"); — programmerj

Use String.Replace()

string path = @"C:\samplec#programs\Converter";
string output = path.Replace("\\", @"\\");
