Method to strip out special characters from a string.

Special characters can cause all kind of trouble.
So here is a method that you pass in a string and all the special characters will be removed.

 

public static string StripSpecialCharacters(string stringToConvert)
        {
            stringToConvert = stringToConvert.Replace("~", string.Empty);
            stringToConvert = stringToConvert.Replace("#", string.Empty);
            stringToConvert = stringToConvert.Replace("%", string.Empty);
            stringToConvert = stringToConvert.Replace("&", string.Empty);
            stringToConvert = stringToConvert.Replace("*", string.Empty);
            stringToConvert = stringToConvert.Replace("{", string.Empty);
            stringToConvert = stringToConvert.Replace("}", string.Empty);
            stringToConvert = stringToConvert.Replace("\\", string.Empty);
            stringToConvert = stringToConvert.Replace(":", string.Empty);
            stringToConvert = stringToConvert.Replace("<", string.Empty);
            stringToConvert = stringToConvert.Replace(">", string.Empty);
            stringToConvert = stringToConvert.Replace("?", string.Empty);
            stringToConvert = stringToConvert.Replace("/", string.Empty);
            stringToConvert = stringToConvert.Replace("|", string.Empty);
            stringToConvert = stringToConvert.Replace("\"", string.Empty);
            return stringToConvert;
        }

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, “Courier New”, courier, monospace;

SharePoint filename special characters not allowed

I was creating files in memory and loading them into a doc library based on user input on a webpart.
Some smart user put special characters in and of course it blew up my web part.

So I had to research what characters are not allowed in file names.

Here they are:
~, #, %, & , *, {, }, \, :, <, >, ?, /, |, “

So I wrote a little function to remove the special characters.

public static string RemoveSpecialCharacters(string stringToConvert)
{
stringToConvert = stringToConvert.Replace(“~”, string.Empty);
stringToConvert = stringToConvert.Replace(“#”, string.Empty);
stringToConvert = stringToConvert.Replace(“%”, string.Empty);
stringToConvert = stringToConvert.Replace(“&”, string.Empty);
stringToConvert = stringToConvert.Replace(“*”, string.Empty);
stringToConvert = stringToConvert.Replace(“{“, string.Empty);
stringToConvert = stringToConvert.Replace(“}”, string.Empty);
stringToConvert = stringToConvert.Replace(“\\”, string.Empty);
stringToConvert = stringToConvert.Replace(“:”, string.Empty);
stringToConvert = stringToConvert.Replace(“<“, string.Empty);
stringToConvert = stringToConvert.Replace(“>”, string.Empty);
stringToConvert = stringToConvert.Replace(“?”, string.Empty);
stringToConvert = stringToConvert.Replace(“/”, string.Empty);
stringToConvert = stringToConvert.Replace(“|”, string.Empty);
stringToConvert = stringToConvert.Replace(“\””, string.Empty);
}

So any filename I was going to use got run through this function to clean it up.
