CodeTypeOfExpression Class
Represents a typeof expression, an expression that returns a Type for a specified type name.
Assembly: System (in System.dll)
A CodeTypeOfExpression represents a typeof expression that returns a Type at runtime.
The Type property specifies the data type to return a Type object for.
Use CodeTypeReferenceExpression to represent source code that refers to a type by name, such as when creating a CodeCastExpression to cast an object to a name-specified type.
The following example demonstrates use of a CodeTypeOfExpression to represent a typeof expression.
' Creates a reference to the System.DateTime type. Dim typeRef1 As New CodeTypeReference("System.DateTime") ' Creates a typeof expression for the specified type reference. Dim typeof1 As New CodeTypeOfExpression(typeRef1) ' Create a Visual Basic code provider Dim provider As CodeDomProvider = CodeDomProvider.CreateProvider("VisualBasic") ' Generate code and send the output to the console provider.GenerateCodeFromExpression(typeof1, Console.Out, new CodeGeneratorOptions()) ' The code generator produces the following source code for the preceeding example code: ' GetType(Date)
