ArgumentException Constructor (String, String)

This constructor initializes the Message property of the new instance using the value of the message parameter. The content of the message parameter is intended to be understood by humans. The caller of this constructor is required to ensure that this string has been localized for the current system culture.

This constructor initializes the ParamName property of the new instance using paramName. The content of paramName is intended to be understood by humans.

The following table shows the initial property values for an instance of ArgumentException.

The following code example demonstrates how to call the ArgumentException constructor. This code example is part of a larger example provided for the ArgumentException class.

static int DivideByTwo(int num) 
{
    // If num is an odd number, throw an ArgumentException. 
    if ((num & 1) == 1)
        throw new ArgumentException("Number must be even", "num");

    // num is even, return half of its value. 
    return num / 2;
}
