以前一直是用C#直接操作Excel,但是发现性能无比低下,最近发现用Excel中的宏可以高速的完成批处理的功能,于是决定写一个用C#为Excel文件创建宏的程序,工程如下:
using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Reflection;
using System.Text;
using Office = Microsoft.Office.Core;
using VBDE = Microsoft.Vbe.Interop;
using Excel = Microsoft.Office.Interop.Excel;
namespace ConsoleApplication1
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
string MyFile = Path.GetFullPath(".") + @"\sample.xls";
CreateWorkbook(MyFile,GetMacro());
Console.WriteLine("File Saved to " + MyFile);
Console.ReadLine();
}
#region Get Macro
private static string GetMacro()
{
StringBuilder sb = new StringBuilder();
sb.Append("Sub FormatSheet()" + "\n");
sb.Append(" msgbox \"http://www.cnblogs.com/huangcong/\"\r\n");
sb.Append("End Sub");
return sb.ToString();
}
#endregion
#region Create Workbook
private static void CreateWorkbook(string FileName,string Macro)
{
Excel.Application xl = null;
Excel._Workbook wb = null;
Excel._Worksheet sheet = null;
VBDE.VBComponent module = null;
bool SaveChanges = false;
try
{
if (File.Exists(FileName)) { File.Delete(FileName); }
GC.Collect();
xl = new Excel.Application();
xl.Visible = false;
wb = (Excel._Workbook)(xl.Workbooks.Add( Missing.Value ));
sheet = (Excel._Worksheet)wb.ActiveSheet;
module = wb.VBProject.VBComponents.Add(VBDE.vbext_ComponentType.vbext_ct_StdModule);
module.CodeModule.AddFromString(Macro);
xl.Visible = false;
xl.UserControl = false;
SaveChanges = true;
wb.SaveAs(FileName,Excel.XlFileFormat.xlWorkbookNormal,
null,null,false,false,Excel.XlSaveAsAccessMode.xlShared,
false,false,null,null,null);
}
catch( Exception theException )
{
String msg;
msg = "Error: ";
msg = String.Concat( msg, theException.Message );
msg = String.Concat( msg, " Line: " );
msg = String.Concat( msg, theException.Source );
Console.WriteLine(msg);
}
finally
{
try
{
xl.Visible = false;
xl.UserControl = false;
wb.Close(SaveChanges,null,null);
xl.Workbooks.Close();
}
catch { }
xl.Quit();
if (module != null) { Marshal.ReleaseComObject (module); }
if (sheet !=null) { Marshal.ReleaseComObject (sheet); }
if (wb !=null) { Marshal.ReleaseComObject (wb); }
if (xl !=null) { Marshal.ReleaseComObject (xl); }
module = null;
sheet=null;
wb=null;
xl = null;
GC.Collect();
}
}
#endregion
}
}

#endregion

}
运行结果:
打开添加了宏的Excel文件,找到刚才创建好的宏:
