CodeTypeOfExpression Class

Represents a typeof expression, an expression that returns a Type for a specified type name.

Namespace:  System.CodeDom
Assembly:  System (in System.dll)
[SerializableAttribute]
[ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch)]
[ComVisibleAttribute(true)]
public class CodeTypeOfExpression : CodeExpression

The CodeTypeOfExpression type exposes the following members.

  NameDescription
Public methodCodeTypeOfExpression()Initializes a new instance of the CodeTypeOfExpression class.
Public methodCodeTypeOfExpression(CodeTypeReference)Initializes a new instance of the CodeTypeOfExpression class.
Public methodCodeTypeOfExpression(String)Initializes a new instance of the CodeTypeOfExpression class using the specified type.
Public methodCodeTypeOfExpression(Type)Initializes a new instance of the CodeTypeOfExpression class using the specified type.

  NameDescription
Public propertyTypeGets or sets the data type referenced by the typeof expression.
Public propertyUserDataGets the user-definable data for the current object. (Inherited from CodeObject.)

  NameDescription
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)

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.
CodeTypeReference typeRef1 = new CodeTypeReference("System.DateTime");

// Creates a typeof expression for the specified type reference.
CodeTypeOfExpression typeof1 = new CodeTypeOfExpression(typeRef1);

// Create a C# code provider
CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");

// 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: 
//    typeof(System.DateTime)
