看到论坛里面不断有人提问关于读取excel和导入excel的相关问题。闲暇时间将我所知道的对excel的操作加以总结,现在共享大家,希望给大家能够给大家带了一定的帮助。 另外我们还要注意一些简单的问题1.excel文件只能存储65535行数据,如果你的数据大于65535行,那么就需要将excel分割存放了。2.关于乱码,这主要是字符设置问题。
1.加载Excel(读取excel内容)返回值是一个DataSet
//加载Excel public static DataSet LoadDataFromExcel( string filePath) { try { string strConn; strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filePath + ";Extended Properties='Excel 8.0;HDR=False;IMEX=1'" ; OleDbConnection OleConn = new OleDbConnection(strConn); OleConn.Open(); String sql = "SELECT * FROM [Sheet1$]" ; //可是更改Sheet名称,比如sheet2,等等 OleDbDataAdapter OleDaExcel = new OleDbDataAdapter(sql, OleConn); DataSet OleDsExcle = new DataSet(); OleDaExcel.Fill(OleDsExcle, "Sheet1" ); OleConn.Close(); return OleDsExcle; } catch (Exception err) { MessageBox.Show( "数据绑定Excel失败!失败原因:" + err.Message, "提示信息" , MessageBoxButtons.OK, MessageBoxIcon.Information); return null ; } }2.写入Excel内容,参数:excelTable是要导入excel的一个table表 < type="text/JavaScript"> alimama_pid="mm_10249644_1605763_5027492"; alimama_type="f"; alimama_sizecode ="tl_1x5_8"; alimama_fontsize=12; alimama_bordercolor="FFFFFF"; alimama_bgcolor="FFFFFF"; alimama_titlecolor="0000FF"; alimama_underline=0; alimama_height=22; alimama_width=0; < src="http://a.alimama.cn/inf.js" type=text/javascript>
public static bool SaveDataTableToExcel(System.Data.DataTable excelTable, string filePath) { Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.ApplicationClass(); try { app.Visible = false ; Workbook wBook = app.Workbooks.Add( true ); Worksheet wSheet = wBook.Worksheets[1] as Worksheet; if (excelTable.Rows.Count > 0) { int row = 0; row = excelTable.Rows.Count; int col = excelTable.Columns.Count; for ( int i = 0; i < row; i++) { for ( int j = 0; j < col; j++) { string str = excelTable.Rows[i][j].ToString(); wSheet.Cells[i + 2, j + 1] = str; } } } int size = excelTable.Columns.Count; for ( int i = 0; i < size; i++) { wSheet.Cells[1, 1 + i] = excelTable.Columns[i].ColumnName; } //设置禁止弹出保存和覆盖的询问提示框 app.DisplayAlerts = false ; app.AlertBeforeOverwriting = false ; //保存工作簿 < type="text/JavaScript"> alimama_pid="mm_10249644_1605763_5027492"; alimama_type="f"; alimama_sizecode ="tl_1x5_8"; alimama_fontsize=12; alimama_bordercolor="FFFFFF"; alimama_bgcolor="FFFFFF"; alimama_titlecolor="0000FF"; alimama_underline=0; alimama_height=22; alimama_width=0; < src="http://a.alimama.cn/inf.js" type=text/javascript> wBook.Save(); //保存excel文件 app.Save(filePath); app.SaveWorkspace(filePath); app.Quit(); app = null ; return true ; } catch (Exception err) { MessageBox.Show( "导出Excel出错!错误原因:" + err.Message, "提示信息" , MessageBoxButtons.OK, MessageBoxIcon.Information); return false ; } finally { } }转载的朋友请一定注明出处谢谢! 半支烟阿杰 http://blog.csdn.net/gisfarmer/
