Code Inspection and Quick-Fixes in ASP.NET
Most of ReSharper's code analysis features are also supported in ASP.NET. You can find the detailed information on these features in the corresponding topics of the Code analysis section. In the main topic of the section, you can also find the feature matrix and check what exactly is supported in ASP.NET.
In this topic, you can find some examples of using code analysis features in ASP.NET.
Various code inspections are available for ASP.NET, including detecting unused import namespaces, unknown symbols and entities, and so on. You can set a severity level for each inspection.
To navigate between code issues that ReSharper discovers, use marker bar and status indicator.
If the locations of files in design time are different from the location where the application is deployed, you can use Path mapping to help ReSharper analyze your code.
During code analysis ReSharper detects and highlights symbols that can't be resolved because the appropriate
Register directives are missing. Also, it offers an easy way to add such directives and fix the problem. ReSharper adds the necessary
Import directive for .NET symbols:
Or a necessary
Register directive for ASP.NET controls:
For more information, refer to Import missing namespaces.
Examples of quick-fixes
Import directive is missing for a type used in the file, ReSharper suggests this quick-fix. After applying the quick-fix, the necessary directive is added.
ReSharper informs you that the
ChangePasswordPushButton_Click method doesn't exist... ...and offers to create one. The method declaration is inserted into the code-behind file or into the current file depending on web page code model (single-file page model or code-behind page model).
The signature of the
ChangePasswordPushButton_Click method doesn't match the signature of the
OnClick event. ReSharper offers a quick-fix to change the signature of the method:
Remove unused directives in file
ReSharper detects unused import namespace directives. As they are unnecessary ReSharper suggests a quick-fix that removes all of them from the current file.
Add Inherits attribute
This quick-fix is specific for ASP.NET directives. The
CodeFile attribute is used together with the
Inherits attribute to associate a code-behind source file with a user control or a page. When the latter is missing, ReSharper suggests a quick-fix:
If there is a
Content control on a content page that is mapped to a missing
ContentPlaceholder on the master page, ReSharper suggests creating the corresponding
ContentPlaceholder control on the corresponding master page. The
ContentPlaceholder control with the corresponding
ID attribute is added to the master page:
