好吧,我想在下一个旁边显示两个文本框customMessageBox.所以我编写了两个文本框.如下.我命名soora,并ayath为它.但在customMessageBox,我不能同时调用两个文本框.它显示错误.如何在下一个旁边显示两个文本框customMessageBox.我只是错误,它是形式Content = soora + ayath

我的C#代码;

TextBox soora = new TextBox();
                soora.Height = 72;
                soora.Width = 150;
                soora.MaxLength = 3;

TextBox ayath = new TextBox();
                ayath.Height = 72;
                ayath.Width = 150;
                ayath.MaxLength = 3;

CustomMessageBox messageBox = new CustomMessageBox()
            {
                Title = "GO TO",

用a container control来容纳两者textboxes

TextBox soora = new TextBox();
                soora.Height = 72;
                soora.Width = 150;
                soora.MaxLength = 3;

TextBox ayath = new TextBox();
                ayath.Height = 72;
                ayath.Width = 150;
                ayath.MaxLength = 3;

StackPanel container = new StackPanel{
                           Orientation = System.Windows.Controls.Orientation.Horizontal
                       };

container.Children.Add(soora);
container.Children.Add(ayath);    

CustomMessageBox messageBox = new CustomMessageBox()
            {
                Title = "GO TO",
                Content = container,
                RightButtonContent = "Go !",
            };
