Use. NET to generate Excel files

Excel| Build Excel
I have encountered some problems with Excel in my work.
On the network to find a lot of methods, each has its pros and cons.
Finally, you chose to use Office Excel Automation services to build Excel files by using the COM objects that Excel provides.
The specific code is as follows:
public static void Createexcel ()
{
for (int i = 0; i<1 i++)
{
String stafile = "d:\\test\\x";
System.Reflection.Missing miss = System.Reflection.Missing.Value;
Excel.applicationclass m_objexcel = new Excel.applicationclass ();
M_objexcel.visible = false;
Excel.Workbooks m_objbooks = (excel.workbooks) m_objexcel.workbooks;
Excel.Workbook m_objbook = (Excel.Workbook) (M_objbooks.add (Miss));
Excel.Worksheet m_objsheet = (excel.worksheet) m_objbook.activesheet;

Writing data to an Excel file
Excel.Range er = m_objsheet.get_range ((object) "A1", System.Reflection.Missing.Value);
Er. Value2 = "DFADFA";
m_objBook.SaveAs (stafile+i.tostring () + ". xls", Miss, Miss, Miss, Miss,miss, Excel.XlSaveAsAccessMode.xlNoChange, Miss , Miss,miss, Miss, Miss);

M_objbook.close (false, Miss, Miss);
M_objbooks.close ();
M_objexcel.quit ();
System.Runtime.InteropServices.Marshal.ReleaseComObject (ER);
System.Runtime.InteropServices.Marshal.ReleaseComObject (M_objsheet);
System.Runtime.InteropServices.Marshal.ReleaseComObject (M_objbook);
System.Runtime.InteropServices.Marshal.ReleaseComObject (m_objbooks);
System.Runtime.InteropServices.Marshal.ReleaseComObject (M_objexcel);
Gc. Collect ();
}
}
A similar approach has been seen on the web, but they all have a problem that cannot be released after using Excel, and after research I have found that when using COM objects, you must release every instance object that you set up, which is the red part of the code.
Note: Use this code to make your own reference to the Excel component in your project. Another: I only did tests under Office 2003 to make sure that the objects could be freed. In other systems did not do the corresponding test, please study on their own.
