String.EndsWith Method (String)
Determines whether the end of this string instance matches the specified string.
Assembly: mscorlib (in mscorlib.dll)
value is a null reference (Nothing in Visual Basic).
This method compares value to the substring at the end of this instance that is the same length as value, and returns an indication whether they are equal. To be equal, value must be a reference to this same instance or match the end of this instance.
This method performs a word (case-sensitive and culture-sensitive) comparison using the current culture.Notes to Callers
As explained in Best Practices for Using Strings in the .NET Framework, we recommend that you avoid calling string comparison methods that substitute default values and instead call methods that require parameters to be explicitly specified. To determine whether a string ends with a particular substring by using the string comparison rules of the current culture, call the EndsWith(String, StringComparison) method overload with a value of StringComparison.CurrentCulture for its comparisonType parameter.
