how to check if a char exists in a string then remove it 1

[Programmer2006]

I have a strings "Foamtreads" and "Mens_Foamtreads"
I have an if else statement
if (there is a dash){
//remove dash
}
I can't figure out my if statement because I am getting an Argument out of Range exception when there is no dash.
if(dashPositioon=strTemp.IndexOfAny('_')!=null)

You can have something like this...

string tmpStr = "Mens_Foamtreads";
int dashPosition = tmpStr.IndexOf("_");
if ( dashPosition > -1)
{
    tmpStr = tmpStr.Remove(dashPosition, 1);
    MessageBox.Show(tmpStr);
}

Sharing the best from my side...

You can also just remove it as a rule. It doesn't hurt anything to do this.

myString.Replace("_", "");

If it is there, it is removed. I can't imagine the impact is any worse than checking the indexof every time. You can also keep adding .Replace() to the end of the string and have a good old time.
