C# 将文本流输出到VS2010输出窗口
我已经为VS2010创建了一个外接程序，它使用一个单独的类来进行一些处理。结果是文本显示在输出窗口的新窗格中 此处理类的构造函数引用由addins Connect类创建的新OutputWindowPane。文本是使用OutputString方法编写的 这可以正常工作，并且文本显示正确，但是，当执行返回到addins Connect类时，所有文本都会在一次更新中显示。我还注意到，当加载项运行时，IDE似乎冻结了。我是addin development的新手，所以我是否错过了一些明显的东西 是否有一种方法可以修改此过程，以便在每次调用OutputString时在输出窗口中更新文本？我希望有某种更新方法，但一直找不到 更新 我注意到这与使用单独的类无关。以下示例说明了我的问题：C# 将文本流输出到VS2010输出窗口,c#,visual-studio-2010,visual-studio,add-in,C#,Visual Studio 2010,Visual Studio,Add In,我已经为VS2010创建了一个外接程序，它使用一个单独的类来进行一些处理。结果是文本显示在输出窗口的新窗格中 此处理类的构造函数引用由addins Connect类创建的新OutputWindowPane。文本是使用OutputString方法编写的 这可以正常工作，并且文本显示正确，但是，当执行返回到addins Connect类时，所有文本都会在一次更新中显示。我还注意到，当加载项运行时，IDE似乎冻结了。我是addin development的新手，所以我是否错过了一些明显的东西 是否有一
