"\" is a escape character in C#. C# usually uses "\\" to denote "\". So, it is not a problem.

I assume you're looking into the variable (in Visual Studio).
I believe (not sure) visual studio displays the raw data and would displays a newline as '\n', thus display a slash as '\\'.
Makes sense, not?

It is in single backslash format.
When you look at any string in the debugger, it shows them with appropriate escape characters: "\n", "\t" and "\\" for newline, tab and a single backslash respectively.

If you think about it, it makes sense: if it didn't you would not be able to tell any difference between
"Hello\nThere"
A single line with a backslash and a lower case 'n' between the words, and
"Hello\nThere"
Two lines, one of "Hello" and one of "There"
In the debugger, these would be shown as:
"Hello\\nThere"
and
"Hello\nThere"
respectively.

string str1 = "123\\456\\789\\10";
string str2 = str1.Replace('\',"");

Won't compile, '' is not a character.
Use str1.Replace("\\", "") instead.
--Edit:--
Sorry my friend, but no overload exists for string.Replace(char, string).

Actually you should use "@" when you want to "\" directly like below,

str1.Replace(@"\","");
MIDL
 try this 
string strText = "as\\fsff\\sfff\\fsf\\";
                Response.Write(strText.Replace("\\",@"\"));

The heck?
You're replacing one character with the same!
.Replace(@"\\",@"\")

Hi,
Thanks for your response. bt in this solution if i am lookion value in debuging mode it display in double slash....
try this, should work

C#
public string removeDoubleBackslashes(string input)
 {
     char[] separator = new char[1] { '\\' };
     string result = "";
     string[] subResult = input.Split(separator);
     for (int i = 0; i <= subResult.Length - 1; i++)
     {
         result = i < subResult.Length - 1 ? result + subResult[i] + "\\" : result + subResult[i];
     }
     return result;
 }
