TypeBinaryExpression Class

A type test is an example of an operation between an expression and a type.

Use the TypeIs factory method to create a TypeBinaryExpression.

The value of the NodeType property of a TypeBinaryExpression object is TypeIs.

The following example creates a TypeBinaryExpression object that represents a type test of a string value against the Int32 type.

// Create a TypeBinaryExpression that represents a 
// type test of the string "spruce" against the 'int' type.
System.Linq.Expressions.TypeBinaryExpression typeBinaryExpression =
    System.Linq.Expressions.Expression.TypeIs(
        System.Linq.Expressions.Expression.Constant("spruce"),
        typeof(int));

Console.WriteLine(typeBinaryExpression.ToString());

// This code produces the following output: 
// 
// ("spruce" Is Int32)
