Exemplos

O exemplo a seguir demonstra o uso de uma CodeTypeOfExpression expressão typeof para representar.

// 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)

' 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)

Comentários

Um CodeTypeOfExpression representa uma typeof expressão que retorna um Type em runtime.

A Type propriedade especifica o tipo de dados para o qual retornar um Type objeto.

Use CodeTypeReferenceExpression para representar o código-fonte que se refere a um tipo por nome, como ao criar um CodeCastExpression objeto para converter um objeto em um tipo especificado pelo nome.
