FindAllIllegalChars example |
The invalidCharPos increments in the last else statment of the example is redudant and could
eventually make the routine miss one illegal character in the userEnteredPath parameter. The
invalidCharPos variable is already incremented by one when passed to the String.IndexOfAny method
at the beginning of the example. When the subsequent increment is made, one character is missed in
the next call to String.IndexOfAny.
I've used example in a routine that replace all illegal characters in a file name with undescores:
private string ReplaceAnyIllegalChars(string OutputFileName)
{
int invalidCharPos = -1;
bool endOfName = false;
bool foundIllegalChars = false;
string fileName = OutputFileName;
while (!endOfName)
{
invalidCharPos = fileName.IndexOfAny(Path.GetInvalidFileNameChars(), invalidCharPos + 1);
if (-1 == invalidCharPos)
{
endOfName = true;
}
else
{
foundIllegalChars = true;
fileName = fileName.Replace(OutputFileName[invalidCharPos], '_');
if (invalidCharPos >= fileName.Length - 1)
{
endOfName = true;
}
}
}
return fileName;
}
