Constructors

	Name	Description
	CodeCastExpression()	Initializes a new instance of the CodeCastExpression class.
	CodeCastExpression(CodeTypeReference^, CodeExpression^)	Initializes a new instance of the CodeCastExpression class using the specified destination type and expression.
	CodeCastExpression(String^, CodeExpression^)	Initializes a new instance of the CodeCastExpression class using the specified destination type and expression.
	CodeCastExpression(Type^, CodeExpression^)	Initializes a new instance of the CodeCastExpression class using the specified destination type and expression.

Properties

	Name	Description
	Expression	Gets or sets the expression to cast.
	TargetType	Gets or sets the destination type of the cast.
	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

CodeCastExpression can be used to represent an expression cast to a different data type or interface.

The Expression property indicates the CodeExpression to cast. The TargetType property indicates the type to cast to.

Examples

This example demonstrates using a CodeCastExpression to cast a System.Int32 value to a System.Int64 data type.

C++

// This CodeCastExpression casts an Int32 of 1000 to an Int64.        

// targetType parameter indicating the target type of the cast.
// The CodeExpression to cast, here an Int32 value of 1000.
CodeCastExpression^ castExpression = gcnew CodeCastExpression( "System.Int64",gcnew CodePrimitiveExpression( 1000 ) );

// A C# code generator produces the following source code for the preceeding example code:
// ((long)(1000));
