Answer 1

xmlns:c="clr-namespace:Converters"

您应该检查Converters类的名称空间，这应该代替Converters。如果Converters是您的班级，那么您应该在.cs文件中放置名称空间后的内容。

示例：

 namepsace MyNamespace {
      public class Converters { }
 }

然后你的XAML将是：

 xmlns:c="clr-namespace:MyNamespace"

额外：如果您想更具体，也可以添加汇编参数。

 xmlns:window="clr-namespace:MyNamespace;assembly=MyNamespace"

可以在构建属性中找到程序集（右键单击“项目”，“属性”，“应用程序”，“程序集信息”）

您的默认命名空间也可以在Build Properties中找到。
