C＃WebBrowser和Excel实例 [英] C# WebBrowser and Excel instance

问题描述

您好，



我使用WebBrowser控件打开Excel文件。



问题如果之前已经有一个打开的Excel，WebBrowser使用相同的Excel（应用程序）实例。



是否有一种方法来指示WebBrowser应该创建一个新的Excel实例？



或者是否可以强制（或阻止）在特定实例中打开新的Excel文件？



谢谢

Hello,

I use a WebBrowser control to open an Excel file.

The problem is that if there is already an open Excel before, the WebBrowser uses the same instance of Excel (Application).

Is there a method to indicate that the WebBrowser should create a new instance of Excel?

Or is it possible to force (or prevent) new Excel files to open in a specific instance?

thank you

推荐答案

如果我理解你的话......



MS Excel是单实例应用程序，这意味着Excel将在同一实例中打开下一个文件。要使用Interop强制创建另一个实例，您需要使用 new 关键字打开它。

If i understand you well...

MS Excel is a single-instance application, which means that Excel will open next file in the same instance. To force creating another instance, using Interop, you need to open it using new keyword.

Excel.Application oExcFirstInstance = new Excel.Application();
Excel.Application oExcSecondInstance = new Excel.Application();

oExcFirstInstance.Workbooks.Open(...);
oExcFirstInstance.Workbooks.Open(...);
oExcFirstInstance.Workbooks.Open(...);

oExcSecondInstance.Workbooks.Open(...);
oExcSecondInstance.Workbooks.Open(...);
oExcSecondInstance.Workbooks.Open(...);
