VBA文本型数字变成数值

sub test()
with activesheet
  .usedrange.numberformatlocal=""
  .usedrange=.usedrange.value
end with
end sub
一般运行一次就可以将全部文本型数字变成数值型了

             Excel.Application excel = new Excel.Application();

             //excel.Visible = true;

             Excel.Workbook book = excel.Workbooks.Open(path + "\\" + fileName

                                 , Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);

             Excel.Workbook book1 = excel.Workbooks.Open(path + "\\Convert"

                 , Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);

             string macroname = "Convert!Convert";

             excel.Run(macroname

                 , Missing.Value

                 , Missing.Value

                 , Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value

                 , Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value

                 , Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);

             book1.Close(false

                 , Missing.Value, Missing.Value);

             Marshal.ReleaseComObject(book1);

             book.Close(true

                 , Missing.Value, Missing.Value);

             Marshal.ReleaseComObject(book);

             excel.Quit();

             Marshal.ReleaseComObject(excel);
