Handle a strange error in ASP. net mvc applications

In today's development, visit Http: // localhost: 1672/member/changepwd/ddWhen the Page always reports such an error:

The view 'changepassword' or its master cocould not be found. The following locations were searched:
~ /Views/member/DD. Master
~ /Views/shared/DD. MasterAfter one afternoon's test, we found the problem was as follows:My actionsCodeIn, the last sentence is: Return view ("changepassword", username );
The original problem is that the second parameter of one of the reload methods in the view method is of the string type, indicating mastername. So I found such an error.Finally, use the view method of a parameter.
