I'm using the Excel interop in C# (ApplicationClass) and have placed the following code in my finally clause:
while (System.Runtime.InteropServices.Marshal.ReleaseComObject(excelSheet) != 0) { }
excelSheet = null;
GC.Collect();
GC.WaitForPendingFinalizers();
Although, this kind of works the Excel.exe process is still in the background even after I close Excel. It is only released once my application is manually closed.
Anyone realize what I am doing wrong, or has an alternative to ensure interop objects are properly disposed of.
Thanks.
