如何基于XML文件自动生成WPF控件？ [英] How to generate WPF controls automatically based on XML file?

问题描述

我有一个Xml文件，该文件告诉我必须添加到表单的控件，但是此Xml动态更改，因此我需要更新表单。
当前，我可以读取XML文件，但是我不知道是否可以基于该文件自动创建表单？

I have an Xml file which tells me the controls that I have to add to a form but this Xml changes dynamically and I need to update the form. Currently, I can read the XML file, but I dont know if it is possible to automatically create forms based on that or not ?

推荐答案

是的。

WPF提供了几种方法

WPF offers several ways of creating controls either in Xaml or in code.

对于您的情况，如果需要动态创建控件，则必须在代码中创建它们。您可以使用它们的构造函数直接创建控件，如下所示：

For your case if you need to dynamically create your controls, you'll have to create them in code. You can either create your control directly using their constructors as in:

        // Create a button.
        Button myButton= new Button();
        // Set properties.
        myButton.Content = "Click Me!";

        // Add created button to a previously created container.
        myStackPanel.Children.Add(myButton);

或者您可以将控件创建为包含xaml的字符串，并使用XamlReader解析该字符串并创建所需的控件：

Or you could create your controls as a string containing xaml and use a XamlReader to parse the string and create the desired control:

        // Create a stringBuilder
        StringBuilder sb = new StringBuilder();

        // use xaml to declare a button as string containing xaml
        sb.Append(@"<Button xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' 
                            xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' ");
        sb.Append(@"Content='Click Me!' />");

        // Create a button using a XamlReader
        Button myButton = (Button)XamlReader.Parse(sb.ToString());

        // Add created button to previously created container.
        stackPanel.Children.Add(myButton);

现在，您要使用的两种方法中的哪一种确实取决于您。

Now for which one of the two methods you want to use really depends on you.
