 //建立Excel对象

            Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();

            excel.Application.Workbooks.Add(true);

            excel.Visible = false;

            excel.SaveWorkspace(path);//FilePath

            //生成字段名称

            for (int i = 0; i < dt.Columns.Count; i++)

            {



                excel.Cells[1, i + 1] = dt.Columns[i].ColumnName;

            }

            //填充数据

            for (int row = 0; row <= dt.Rows.Count - 1; row++)

            {

                for (int column = 0; column < dt.Columns.Count; column++)

                {



                    if (dt.Rows[row][column].GetType() == typeof(string))

                    {

                        excel.Cells[row + 2, column + 1] = "'" + dt.Rows[row][column].ToString();

                    }

                    else

                    {
