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