The specified x:Name becomes the name of a field that is created in the underlying code when XAML is processed, and that field holds a reference to the object. In Silverlight, using the managed API, the process of creating this field is performed by the MSBuild target steps, which also are responsible for joining the partial classes for a XAML file and its code-behind. This behavior is not necessarily XAML-language specified; it is the particular implementation that Silverlight applies to use x:Name in its programming and application models.

Name can also be set using property element syntax with inner text, but that is uncommon. In contrast, x:Name cannot be set in XAML property element syntax, or in code using SetValue; it can only be set using attribute syntax on objects because it is a directive. If Name is available as a property on the class, Name and x:Name can be used interchangeably as attributes, but a parse exception will result if both are specified on the same element. If the XAML is markup compiled, the exception will occur on the markup compile, otherwise it occurs on load.

它们不是一回事。

x:Name是一个xaml概念，主要用于引用元素。当您为元素赋予x:Name xaml属性时，“指定的x:Name将成为处理xaml时在底层代码中创建的字段的名称，并且该字段包含对该对象的引用。”因此，它是一个由设计器生成的字段，默认情况下具有内部访问权限。

Name是FrameworkElement的现有字符串属性，以xaml属性的形式列出，与任何其他wpf元素属性一样。

因此，这也意味着x:Name可以用于更广泛的对象。这是一种使xaml中的任何东西都可以通过给定名称引用的技术。

其中一个答案是x:name将在不同的程序语言中使用，如c#，而name将用于框架。说实话，我听起来就是这样。

我总是使用x:Name变量。 我不知道这是否会影响性能，我只是觉得它更容易，原因如下。 如果您有自己的用户控件驻留在另一个程序集中，只有“Name”属性并不总是足够的。这使得使用x:Name属性更加容易。
