엑셀 조작 방법
15403 단어 Excel
첫 번 째: html 코드 를 직접 인쇄 한 다음 에 출력 형식 을 엑셀 파일 로 위장 합 니 다 (엑셀 은 xml 과 html 코드 를 식별 할 수 있 습 니 다)
코드 예시:
/// <summary>
/// html excel
/// ： ， 、
/// ： excel excel ， 。 html
/// ： excel
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void BtnHtml_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode("HtmlExcel.xls", Encoding.UTF8).ToString());
Response.ContentType = "application/ms-excel";
PageInfo<VW_CLN_LendAfter_CustDetail> PageToPtint = ViewEntitiy.VW_CLN_LendAfter_CustDetail.Query(0, 15, "select * from VW_CLN_LendAfter_CustDetail where 1=1 ", ToList);
DataSoucre = (DataSet)PageToPtint.DataList;
DataTable dt = DataSoucre.Tables[0];
foreach(string key in TotableDC.Keys)
{
if (dt.Columns.Contains(key))
{
dt.Columns[key].ColumnName = TotableDC[key];
}
}
StringBuilder strexcel = new StringBuilder();
strexcel.Append(@"<table><tr>");
//
foreach(DataColumn dc in dt.Columns)
{
if (TotableDC.Values.Contains(dc.ColumnName))
{
strexcel.Append(@"<th>" + dc.ColumnName + "</th>");
}
}
strexcel.Append(@"</tr>");
//
foreach (System.Data.DataRow dr in dt.Rows)
{
strexcel.Append(@"<tr>");
foreach(System.Data.DataColumn dc in dt.Columns)
{
if (TotableDC.Values.Contains(dc.ColumnName))
{
strexcel.Append(@"<td>" + dr[dc.ColumnName] + @"</td>");
}
}
strexcel.Append(@"</tr>");
}
strexcel.Append(@"<table>");
Response.Write("<meta http-equiv=\"content-type\" content=\"application/ms-excel; charset=utf-8\"/>" + strexcel);
Response.End();
}
두 번 째: Appliction 으로 엑셀 내 보 내기 여기 서 말 하 는 Applcation 은 마이크로소프트 가 제공 하 는 OFFICE DOM 구성 요소 입 니 다.이런 장점 과 결점 은 모두 매우 뚜렷 하 다.
코드 예제:
/// <summary>
/// Appliction excel
/// ： ， Excel
/// ： excel ，IIS ， ， ，
/// ： excel ，
/// </summary>

finally

workbook = null;
xlApp.Quit();
xlApp = null;
}
Response.WriteFile(Server.MapPath( "b .XLS"));
Response.End();
}
세 번 째: ADO. NET 을 사용 하여 sql 링크 를 진행 합 니 다.

네 번 째, 제3자 구성 요 소 를 사용 합 니 다. 제3자 구성 요 소 는 여러 가지 가 있 습 니 다. 제 가 사용 하 는 것 은 aspose. cell 구성 요소 입 니 다.
코드 예제:
/// <summary>
/// Aspose excel
/// ： ， ， ， ，
/// ： ， ， .net
/// ： .net4.0 ， .net 3.5 ，3.5
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void BtnAspose_Click(object sender, EventArgs e)
{
Aspose.Cells.Workbook Worbook = new Aspose.Cells.Workbook("b .XLS");
Worksheet sheet = Worbook.Worksheets[0];
Cells cell = sheet.Cells;
PageInfo<VW_CLN_LendAfter_CustDetail> PageToPtint = ViewEntitiy.VW_CLN_LendAfter_CustDetail.Query(0, 15, "select * from VW_CLN_LendAfter_CustDetail where 1=1 ", ToList);
DataSoucre = (DataSet)PageToPtint.DataList;
DataTable dt = DataSoucre.Tables[0].Copy();
foreach (string key in TotableDC.Keys)
{
if (dt.Columns.Contains(key))
{
dt.Columns[key].ColumnName = TotableDC[key];
}
}
// Aspose.CELLS F12
// dt 0 0 Word ， TRUE
cell.ImportDataTable(dt, true, 0, 0);
// ， xls xlsx
XlsSaveOptions saveOptions = new XlsSaveOptions() ;
saveOptions.SaveFormat = SaveFormat.Xlsx;
// Worbook.Save(Response, SaveFormat.Xlsx, ContentDisposition.Attachment, new SaveOptions(){ SaveType = SaveType.OpenInExcel, SaveFormat=SaveFormat.Xlsx, ClearData=true, CachedFileFolder="AsposeExcel.xlsx"});
// Worbook.Save(@ )
Worbook.Save(Response,"BaoBiao.xlsx", ContentDisposition.Attachment,saveOptions);
//Aspose
