Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type String. When you use instance method syntax to call this method, omit the first parameter. For more information, see https://msdn.microsoft.com/en-us/library/bb384936(v=vs.111) or https://msdn.microsoft.com/en-us/library/bb383977(v=vs.111).
Remarks
For more information about how to use this method, see the AsInt() topic. If you pass a non-numeric string value, an empty string (""), null reference (Nothing in Visual Basic), or a value outside the range of the specified type, the method returns 0. To avoid ambiguity about what the returned value means, call the IsInt(String) method first to check whether the input string can be converted to an integer value.
