將gridview數據導出爲CSV文件

Question

我在ASP.Net 2.0中有一個gridview控件，我需要將這個gridview數據導出爲CSV文件。

我已經綁定了這個gridview和數據集。將數據集綁定到gridview之後，我在gridview數據中做了一些修改，就好像我在數據集中得到0一樣，然後我在gridview中顯示0作爲「Started」，如果我在數據集中得到1，然後在gridview中將1顯示爲「Not Started」。

所以，我不能直接使用數據集來導出。我需要的是...... 我想要將我的gridview數據（不是數據集的數據）導出到CSV文件中的代碼（在c＃中）。

Answer 1

請嘗試下面的代碼，我已經使用過很多次了。它會將數據直接從gridview導出到代碼中指定的csv文件中。

protected void btnExportCSV_Click(object sender, EventArgs e) 
{ 
    Response.Clear(); 
    Response.Buffer = true; 
    Response.AddHeader("content-disposition", 
    "attachment;filename=GridViewExport.csv"); 
    Response.Charset = ""; 
    Response.ContentType = "application/text"; 

    GridView1.AllowPaging = false; 
    GridView1.DataBind(); 

    StringBuilder sb = new StringBuilder(); 
    for (int k = 0; k < GridView1.Columns.Count; k++) 
    { 
     //add separator 
     sb.Append(GridView1.Columns[k].HeaderText + ','); 
    } 
    //append new line 
    sb.Append("\r\n"); 
    for (int i = 0; i < GridView1.Rows.Count; i++) 
    { 
     for (int k = 0; k < GridView1.Columns.Count; k++) 
     { 
      //add separator 
      sb.Append(GridView1.Rows[i].Cells[k].Text + ','); 
     } 
     //append new line 
     sb.Append("\r\n"); 
    } 
    Response.Output.Write(sb.ToString()); 
    Response.Flush(); 
    Response.End(); 
}

首先感謝Devjosh爲我修改與擁有的AutoGenerateColumns =真正的和AllowSorting =真GridView的工作中很好的答案。另外，我從數據中刪除了任何返回的逗號，以確保csv文件沒有損壞。

private void ExportReport() 
{ 
    // set the resulting file attachment name to the name of the report... 
    string fileName = "test"; 

    Response.Clear(); 
    Response.Buffer = true; 
    Response.AddHeader("content-disposition", "attachment;filename=" + fileName + ".csv"); 
    Response.Charset = ""; 
    Response.ContentType = "application/text"; 

    System.Text.StringBuilder sb = new System.Text.StringBuilder(); 

    // Get the header row text form the sortable columns 
    LinkButton headerLink = new LinkButton(); 
    string headerText = string.Empty; 

    for (int k = 0; k < gvReport.HeaderRow.Cells.Count; k++) 
    { 
     //add separator 
     headerLink = gvReport.HeaderRow.Cells[k].Controls[0] as LinkButton; 
     headerText = headerLink.Text; 
     sb.Append(headerText + ","); 
    } 
    //append new line 
    sb.Append("\r\n"); 
    for (int i = 0; i < gvReport.Rows.Count; i++) 
    { 
     for (int k = 0; k < gvReport.HeaderRow.Cells.Count; k++) 
     { 
      //add separator and strip "," values from returned content... 

      sb.Append(gvReport.Rows[i].Cells[k].Text.Replace(",", "") + ","); 
     } 
     //append new line 
     sb.Append("\r\n"); 
    } 
    Response.Output.Write(sb.ToString()); 
    Response.Flush(); 
    Response.End(); 
}

private void ExportGridToCSV() 
     {    
      Response.Clear(); 
      Response.Buffer = true; 
      Response.AddHeader("content-disposition", "attachment;filename=Employee.csv"); 
      Response.Charset = ""; 
      Response.ContentType = "application/text"; 
      GridEmployee.AllowPaging = false; 
      GridEmployee.DataBind(); 

      StringBuilder columnbind = new StringBuilder(); 
      for (int k = 0; k < GridEmployee.Columns.Count; k++) 
      { 

       columnbind.Append(GridEmployee.Columns[k].HeaderText + ','); 
      } 

      columnbind.Append("\r\n"); 
      for (int i = 0; i < GridEmployee.Rows.Count; i++) 
      { 
       for (int k = 0; k < GridEmployee.Columns.Count; k++) 
       { 

        columnbind.Append(GridEmployee.Rows[i].Cells[k].Text + ','); 
       } 

       columnbind.Append("\r\n"); 
      } 
      Response.Output.Write(columnbind.ToString()); 
      Response.Flush(); 
      Response.End(); 

     }
