XMLDocument替换不起作用

Question

XML替换对我不起作用。调试时如果我按 Shift + F9 ，它被替换为值但不能直接调试。 我的An exception of type 'System.InvalidOperationException' occurred in EntityFramework.dll but was not handled in user code Additional information: The model backing the '<modelName> ' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269). 代码值中有很多%26amp;，我希望一起替换所有内容。

innerXML

请告诉我那里发生的事情。
