                  问题描述

                  限时送ChatGPT账号..

                  我想创建一个 VS 扩展,我需要知道调用菜单的行号.我找到了一个 VisualBasic 实现,其中的宏似乎 这样做,但我不知道如何在 C# 中启动它.目标是知道调用 ContextMenu 的行的确切编号,以便在其上放置一个占位符图标,就像一个断点一样.感谢有用的链接,因为我在这个主题上找不到太多.

                  I would like to create a VS extension in which I need to know the line number the menu was called on. I found a VisualBasic implementation with a macro that seems to do this, but I don't know how to start this in C#. The goal would be to know the exact number of the line the ContextMenu was called on to put a placeholder icon on it just like a break point. Useful links are appreciated since I couldn't find much on this topic.

                  您可以创建一个 VSIX 项目并在您的项目中添加一个 Command 项.然后在 MenuItemCallback() 方法中添加如下代码,获取代码行号.

                  You could create a VSIX project and add a Command item in your project. Then add following code in MenuItemCallback() method to get the code line number.

                      private void MenuItemCallback(object sender, EventArgs e)
                      {
                          EnvDTE.DTE dte = (EnvDTE.DTE)this.ServiceProvider.GetService(typeof(EnvDTE.DTE));
                  
                          EnvDTE.TextSelection ts = dte.ActiveWindow.Selection as EnvDTE.TextSelection;
                          if (ts == null)
                              return;
                          EnvDTE.CodeFunction func = ts.ActivePoint.CodeElement[vsCMElement.vsCMElementFunction]
                                      as EnvDTE.CodeFunction;
                          if (func == null)
                              return;
                  
                          string message = dte.ActiveWindow.Document.FullName + System.Environment.NewLine +
                            "Line " + ts.CurrentLine + System.Environment.NewLine +
                            func.FullName;
                  
                          string title = "GetLineNo";
                  
                          VsShellUtilities.ShowMessageBox(
                              this.ServiceProvider,
                              message,
                              title,
                              OLEMSGICON.OLEMSGICON_INFO,
                              OLEMSGBUTTON.OLEMSGBUTTON_OK,
                              OLEMSGDEFBUTTON.OLEMSGDEFBUTTON_FIRST);
                      }
