示例
下面的代码示例演示了如何使用此方法来获取 SecurityCallContext 描述方法调用的安全上下文的 对象。
// Set the employee's salary. Only managers can do this.
void SetSalary( double ammount )
{
if ( SecurityCallContext::CurrentCall->IsCallerInRole( "Manager" ) )
{
salary = ammount;
}
else
{
throw gcnew UnauthorizedAccessException;
}
}
// Set the employee's salary. Only managers can do this.
public void SetSalary (double ammount)
{
if (SecurityCallContext.CurrentCall.IsCallerInRole("Manager"))
{
salary = ammount;
}
else
{
throw new UnauthorizedAccessException();
}
}
' Set the employee's salary. Only managers can do this.
Public Sub SetSalary(ByVal ammount As Double)
If SecurityCallContext.CurrentCall.IsCallerInRole("Manager") Then
salary = ammount
Else
Throw New UnauthorizedAccessException()
End If
End Sub
注解
静态 CurrentCall 属性是访问安全调用上下文的建议方法。
