Příklady

Tento příklad ukazuje použití objektu CodeThrowExceptionStatement k vyvolání nového System.Exceptionobjektu .

// This CodeThrowExceptionStatement throws a new System.Exception.
array<CodeExpression^>^temp0;
CodeThrowExceptionStatement^ throwException = gcnew CodeThrowExceptionStatement( gcnew CodeObjectCreateExpression( gcnew CodeTypeReference( System::Exception::typeid ),temp0 ) );

// A C# code generator produces the following source code for the preceeding example code:
// throw new System.Exception();

// This CodeThrowExceptionStatement throws a new System.Exception.
CodeThrowExceptionStatement throwException = new CodeThrowExceptionStatement(
    // codeExpression parameter indicates the exception to throw.
    // You must use an object create expression to new an exception here.
    new CodeObjectCreateExpression(
    // createType parameter inidicates the type of object to create.
    new CodeTypeReference(typeof(System.Exception)),
    // parameters parameter indicates the constructor parameters.
    new CodeExpression[] {} ) );

// A C# code generator produces the following source code for the preceeding example code:

// throw new System.Exception();

 ' This CodeThrowExceptionStatement throws a new System.Exception.
 ' The codeExpression parameter indicates the exception to throw.
 ' You must use an object create expression to new an exception here.
 Dim throwException As New CodeThrowExceptionStatement( _
New CodeObjectCreateExpression( _
    New CodeTypeReference(GetType(System.Exception)), _
    New CodeExpression() {}))

 ' A Visual Basic code generator produces the following source code for the preceeding example code:

 ' Throw New System.Exception

Poznámky

CodeThrowExceptionStatement může představovat příkaz, který vyvolá výjimku. Výraz by měl být (neboli vyhodnotit) odkazem na instanci typu, který je odvozen z Exception třídy .

Vlastnost ToThrow určuje výjimku, která se má vyvolat.
