如何将我的导出格式设置为microsoft.office.interop.excel中的excel工作簿？

Question

我有这个导出功能，允许我在一个excel中将2个网格视图导出为2个独立的工作表。

但我的问题是：

1. 我怎么能有一个像往常一样下载一个常用的弹出窗口，当我出口按钮，点击提示用户打开，另存为，取消下载，而不是将其保存的到一个特定的位置（目前我在我的代码中做什么）？

2. 如何设置代码以启用所有单元格的wraptext = true，并自动格式化列高和宽以固定所有文本，以便它不显示######日期为例如，当excel打开时，列宽太小。

保护无效EXPORT_BUTTON_Click（对象发件人，EventArgs的） { Microsoft.Office.Interop.Excel._Application应用=新Microsoft.Office.Interop.Excel.Application（）; //在Excel应用程序中创建新的WorkBook Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add（Type.Missing）;

String DT1 = "Data table 1"; 
String DT2 = "Data table 2"; 

ExportToExcel(app, workbook, Gridview1, DT1, 1); 

ExportToExcel(app, workbook, Gridview2, DT2, 2); 

} 
public void ExportToExcel(Microsoft.Office.Interop.Excel._Application app, Microsoft.Office.Interop.Excel._Workbook workbook, GridView gridview, string SheetName, int sheetid) 
{ 

// see the excel sheet behind the program 
app.Visible = true; 

// get the reference of first sheet. By default its name is Sheet1. 
// store its reference to worksheet 

worksheet = (Excel.Worksheet)workbook,Worksheets.Add(); 

// changing the name of active sheet 
worksheet.Name = SheetName; 

// storing header part in Excel 
for (int i = 1; i < gridview.Columns.Count + 1; i++) 
{ 
    worksheet.Cells[1, i] = gridview.Columns[i - 1].HeaderText;

     worksheet.Cells[i + 2, j + 1] = gridview.Rows[i].Cells[j].Text.ToString(); 
    }

//save the application 

workbook.SaveAs(@"C:\Users\test\Desktop\Test\" + datetime.ToString("dd-MM-yyyy_hh-mm-ss") + ".xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing); 
      } 
} 

Answer 1

修改Excel文件的路径保存到虚拟路径如下

workbook.SaveAs(@"C:\Users\test\Desktop\Test\" + datetime.ToString("dd-MM-yyyy_hh-mm-ss") + ".xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing); 

将其更改为

workbook.SaveAs(@"~/ExcelFiles/Filename.xlsx" + datetime.ToString("dd-MM-yyyy_hh-mm-ss") + ".xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing); 

尝试下面的代码显示另存为对话框

String FileName = "FileName.xlsx"; 
String FilePath = "~/ExcelFiles/FileName.xlsx"; 
System.Web.HttpResponse response = System.Web.HttpContext.Current.Response; 
response.ClearContent(); 
response.Clear(); 
response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; 
response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ";"); 
response.TransmitFile(FilePath); 
response.Flush(); 
response.End(); 

Answer 2

试试这个：在工作簿您没有添加

Excel.Worksheet worksheet =(Excel.Worksheet)workbook.Worksheets["Sheet" + sheetid]; 

Answer 3

工作

试试下面的代码

工作表=（Excel._Worksheet）oXL.Worksheets.Add（） ;

worksheet.Name = SheetName;

使用RANGS

string[] colNames = new string[gv.Columns.Count]; 

    int col = 0; 

    foreach(gvvolumns dc in GridView.Columns) 
    colNames[col++] = dc.ColumnName; 

    char lastColumn = (char)(65 + dtProducts.Columns.Count - 1); 

    oSheet.get_Range("A1", lastColumn + "1").Value2 = colNames; 
    oSheet.get_Range("A1", lastColumn + "1").Font.Bold = true; 
    oSheet.get_Range("A1", lastColumn + "1").VerticalAlignment 
     = Excel.XlVAlign.xlVAlignCenter; 

Answer 4

由Laxmikant规定的修改方法 “ExportToExcel” 如下的代码设置你的头。

public void ExportToExcel(Microsoft.Office.Interop.Excel._Application app, Microsoft.Office.Interop.Excel._Workbook workbook, GridView gridview, string SheetName, int sheetid) 
{ 

// see the excel sheet behind the program 
app.Visible = true; 

worksheet = (Excel.Worksheet)workbook.Worksheets.Add(); 

// changing the name of active sheet 
worksheet.Name = SheetName; 

// storing header part in Excel 
for (int i = 1; i < gridview.Columns.Count + 1; i++) 
{ 
    worksheet.Cells[1, i] = gridview.Columns[i - 1].HeaderText; 
} 

// storing Each row and column value to excel sheet 
for (int i = 0; i < gridview.Rows.Count - 1; i++) 
{ 
    for (int j = 0; j < gridview.Columns.Count; j++) 
    { 
     worksheet.Cells[i + 2, j + 1] = gridview.Rows[i].Cells[j].Text.ToString(); 
    } 
} 

我删除的这两行代码，现在也没有必要参数的“Sheetid”

Excel.Worksheet worksheet =(Excel.Worksheet)workbook.Worksheets["Sheet" + sheetid]; 
worksheet = workbook.ActiveSheet; 

希望这将解决您的问题
