How to make String.Contains case insensitive? [duplicate]
How can I make the following case insensitive?
myString1.Contains("AbC")
You can create your own extension method to do this:
public static bool Contains(this string source, string toCheck, StringComparison comp)
{
return source != null && toCheck != null && source.IndexOf(toCheck, comp) >= 0;
}
And then call:
mystring.Contains(myStringToCheck, StringComparison.OrdinalIgnoreCase);
You can use:
if (myString1.IndexOf("AbC", StringComparison.OrdinalIgnoreCase) >=0) {
//...
}
This works with any .NET version.
