我尝试了Visual Studio Project Renamer，但是，它在我尝试的少数情况下抛出异常。

我在CopyWiz上取得了很大的成功。

我与他们没有任何关系，我还没有为它付钱，但我可能很快就要为它付钱了，因为它似乎是唯一一个对我的c#和c++项目都有效的工具。我确实希望他们能赚点钱，并继续改进它。

The Rename operations in Visual Studio only change the filename, i.e. *.prj for a project, and *.sln for a solution. You will need to rename folders separately using the filesystem, and you will need to remove and re-add the projects since they will have new folder names. However, note that the solution and project files are respectively text and xml files. You could write your own program that parses them and renames both the folder names, filenames, and fixes the project/solution files internally.

如果您正在Visual Studio 2010中创建网站。您可以按照如下方式修改项目名称。

步骤1:在Visual Studio 2010中，SLN文件将存储在Visual Studio 2010的项目文件夹下，源文件存储在Visual Studio 2010的网站文件夹下。

步骤2:重命名文件夹右键单击该文件夹通过重命名，其中包含您的SLN项目。

步骤3:重命名SLN文件名右键单击该SLN文件转发重命名。

第四步:在Visual Studio 2010的Website下重命名包含SLN文件Source的文件夹。

步骤5:然后最后双击您的SLN文件，并更改您的SLN源文件夹的根。

重命名一个解决方案:

In Solution Explorer, right-click the project, select Rename, and enter a new name. In Solution Explorer, right-click the project and select Properties. On the Application tab, change the "Assembly name" and "Default namespace". In the main cs file (or any other code files), rename the namespace declaration to use the new name. For this right-click the namespace and select Refactor > Rename enter a new name. For example: namespace WindowsFormsApplication1 Change the AssemblyTitle and AssemblyProduct in Properties/AssemblyInfo.cs. [assembly: AssemblyTitle("New Name Here")] [assembly: AssemblyDescription("")] [assembly: AssemblyConfiguration("")] [assembly: AssemblyCompany("")] [assembly: AssemblyProduct("New Name Here")] [assembly: AssemblyCopyright("Copyright © 2013")] [assembly: AssemblyTrademark("")] [assembly: AssemblyCulture("")] Delete bin and obj directories physically. Rename the project physical folder directory. Open the SLN file (within notepad or any editor) and change the path to the project. Clean and Rebuild the project.
