使用intreop库的另一种替代方法是 http://code.google.com/p/excellibrary/，它不需要您安装excel或excel.dll并将其注册到要安装它的计算机或服务器上.>

I am trying to open an Excel file from my C# code.

workBook = workBooks.Open(fileName,               //filename
                          0,                      //updatelinks
                          true,                   //readonly
                          5,                      //format
                          "",                     //password
                          "",                     //WriteResPassword
                          true,                   //IgnoreReadOnlyRecommended
                          XlPlatform.xlWindows,   //Origin
                          "\t",                   //Delimiter
                          false,                  //Editable
                          false,                  //Notify
                          0,                      //Converter
                          true,                   //AddToMru
                          1,                      //Local
                          0);                     //CorruptLoad

I see that the code hangs at workBooks.Open if the excel has some error within it. I have kept the display property to true and that is when I noticed that there is an error in the excel. On further investigation I got to know that the error is caused due to some vba code in the excel which is failing. My requirement is how do I get my C# code to be notified about this, so that it can ignore the error within the file or ignore the file itself?

Another alternative to using the intreop library is http://code.google.com/p/excellibrary/ which doesn't require you to have excel or the excel.dll installed and registered to your machine or server that you are putting it on.
