Exempel

I följande exempel visas hur du använder en CodeTypeOfExpression för att representera ett typav uttryck.

// 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)

Kommentarer

A CodeTypeOfExpression representerar ett typeof uttryck som returnerar ett Type vid körning.

Egenskapen Type anger den datatyp som ett Type objekt ska returneras för.

Använd CodeTypeReferenceExpression för att representera källkod som refererar till en typ efter namn, till exempel när du skapar en CodeCastExpression för att omvandla ett objekt till en namnspecifik typ.
