有没有办法将 ContentControl 转换为这个

如何解决有没有办法将 ContentControl 转换为这个

我试图在 CS 中实现 XAML。它成功了，但只有一件事我无法解决，那就是：将其转换为 ContentControl。

            object parent = this;
        MessageBoxEx.SetParentwindow(this);

必须设置父窗口，否则我会得到一个空引用。

有人可以帮我吗？

找到解决方案

public void InitMessageBox()
    {
        // Create the ElementHost control for hosting the
        // WPF UserControl.
        ContentControl host = new ContentControl();

        host.DataContext = this;
        //host.Dock = DockStyle.Fill;

        // Create the WPF UserControl.
        MessageBoxEx uc =
            new MessageBoxEx();

        // Assign the WPF UserControl to the ElementHost control's
        // Child property.
        //host.Parent = this;
        //host.Child = uc;

        // Add the ElementHost control to the form's
        // collection of child controls.
        //this.Controls.Add(host);

        // p = (ContentControl) this;
        MessageBoxEx.SetParentwindow(host);
        MessageBoxEx.SetMessageForeground(Colors.White);
        MessageBoxEx.SetMessageBackground(Colors.Black);
        MessageBoxEx.SetButtonBackground(MessageBoxEx.ColorFromString("#333333"));
        MessageBoxEx.SetButtonTemplateName("AefCustomButton");
        MessageBoxEx.SetMaxFormWidth(600);
        MessageBoxEx.SetErrorDelegate(new ErrorMsgDelegate());
        // if you want to make the MessageBoxEx silent when you use icons,uncomment the next line
        //MessageBoxEx.SetAsSilent(true);
    }

解决方法

我没有这样做，但您必须遵循特殊的过程才能在 Windows 窗体中使用 WPF 控件。请参阅此链接：Use WPF controls in Windows Forms apps

我找到了一些代码：

        public void InitMessageBox()
    {
        // Create the ElementHost control for hosting the
        // WPF UserControl.
        ElementHost host = new ElementHost();
        host.Dock = DockStyle.Fill;

        // Create the WPF UserControl.
        MsgBoxEx.MessageBoxEx uc =
            new MsgBoxEx.MessageBoxEx();

        // Assign the WPF UserControl to the ElementHost control's
        // Child property.
        host.Parent = this;
        host.Child = uc; // Error

        // Add the ElementHost control to the form's
        // collection of child controls.
        this.Controls.Add(host); // host = error

        // p = (ContentControl) this;
        MessageBoxEx.SetParentWindow(uc);
        MessageBoxEx.SetMessageForeground(Colors.White);
        MessageBoxEx.SetMessageBackground(Colors.Black);
        MessageBoxEx.SetButtonBackground(MessageBoxEx.ColorFromString("#333333"));
        MessageBoxEx.SetButtonTemplateName("AefCustomButton");
        MessageBoxEx.SetMaxFormWidth(600);
        MessageBoxEx.SetErrorDelegate(new ErrorMsgDelegate());
        // if you want to make the MessageBoxEx silent when you use icons,uncomment the next line
        //MessageBoxEx.SetAsSilent(true);
    }

我从网上得到的这个代码但不起作用
