Constructors

	Name	Description
	CodeTypeOfExpression()	Initializes a new instance of the CodeTypeOfExpression class.
	CodeTypeOfExpression(CodeTypeReference^)	Initializes a new instance of the CodeTypeOfExpression class.
	CodeTypeOfExpression(String^)	Initializes a new instance of the CodeTypeOfExpression class using the specified type.
	CodeTypeOfExpression(Type^)	Initializes a new instance of the CodeTypeOfExpression class using the specified type.

Properties

	Name	Description
	Type	Gets or sets the data type referenced by the typeof expression.
	UserData	Gets the user-definable data for the current object.(Inherited from CodeObject.)

Methods

	Name	Description
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Remarks

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.

Examples

The following example demonstrates use of a CodeTypeOfExpression to represent a typeof expression.

C++

// Creates a reference to the System.DateTime type.
CodeTypeReference^ typeRef1 = gcnew CodeTypeReference("System.DateTime");

// Creates a typeof expression for the specified type reference.
CodeTypeOfExpression^ typeof1 = gcnew 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, gcnew CodeGeneratorOptions());
// The code generator produces the following source code for the preceeding example code:
//    typeof(System.DateTime)
