NameDescription
System_CAPS_pubmethodCodeTypeOfExpression()

Initializes a new instance of the CodeTypeOfExpression class.

System_CAPS_pubmethodCodeTypeOfExpression(CodeTypeReference)

Initializes a new instance of the CodeTypeOfExpression class.

System_CAPS_pubmethodCodeTypeOfExpression(String)

Initializes a new instance of the CodeTypeOfExpression class using the specified type.

System_CAPS_pubmethodCodeTypeOfExpression(Type)

Initializes a new instance of the CodeTypeOfExpression class using the specified type.

NameDescription
System_CAPS_pubpropertyType

Gets or sets the data type referenced by the typeof expression.

System_CAPS_pubpropertyUserData

Gets the user-definable data for the current object.(Inherited from CodeObject.)

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(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)
