[英]How to export from datatable to excel file in wpf c#
我有一个数据表,并希望将其导出到excel文件,这是一个wpf应用程序,我发现的所有解决方案都适用于web应用程序asp.net,请帮忙...
just to make it better visible, for all 只是为了让所有人都更好看
Microsoft.Office.Interop.Excel.Application excel = null;
Microsoft.Office.Interop.Excel.Workbook wb = null;
object missing = Type.Missing;
Microsoft.Office.Interop.Excel.Worksheet ws = null;
Microsoft.Office.Interop.Excel.Range rng = null;
try
{
excel = new Microsoft.Office.Interop.Excel.Application();
wb = excel.Workbooks.Add();
ws = (Microsoft.Office.Interop.Excel.Worksheet)wb.ActiveSheet;
for (int Idx = 0; Idx < dt.Columns.Count; Idx++)
{
ws.Range["A1"].Offset[0, Idx].Value = dt.Columns[Idx].ColumnName;
}
for (int Idx = 0; Idx < dt.Rows.Count; Idx++)
{ // <small>hey! I did not invent this line of code,
// I found it somewhere on CodeProject.</small>
// <small>It works to add the whole row at once, pretty cool huh?</small>
ws.Range["A2"].Offset[Idx].Resize[1, dt.Columns.Count].Value =
dt.Rows[Idx].ItemArray;
}
excel.Visible = true;
wb.Activate();
}
catch (COMException ex)
{
MessageBox.Show("Error accessing Excel: " + ex.ToString());
}
catch (Exception ex)
{
MessageBox.Show("Error: " + ex.ToString());
}
You can save a .csv(Comma Seperated Value File) from your datatable. 您可以从数据表中保存.csv(逗号分隔值文件)。 This file can then be opened in Excel.
然后可以在Excel中打开该文件。
Moreover: Whether it is WPF or Winforms, converting is same in both because its conversion code is written in your language ie C# and is not specific to WPF or Winforms. 而且:无论是WPF还是Winforms,转换都是相同的,因为其转换代码是用您的语言(即C#)编写的,并且不特定于WPF或Winforms。
For me Work fine thank you ... some one like vb.net ? 对我来说,很好,谢谢。。。
Dim excel As Microsoft.Office.Interop.Excel.Application = Nothing
Dim wb As Microsoft.Office.Interop.Excel.Workbook = Nothing
Dim missing As Object = Type.Missing
Dim ws As Microsoft.Office.Interop.Excel.Worksheet = Nothing
Dim rng As Microsoft.Office.Interop.Excel.Range = Nothing
Sub ExcelFile(ByVal dt As DataTable) 子ExcelFile(ByVal dt作为DataTable)
Try
excel = New Microsoft.Office.Interop.Excel.Application()
wb = excel.Workbooks.Add()
ws = DirectCast(wb.ActiveSheet, Microsoft.Office.Interop.Excel.Worksheet)
For Idx As Integer = 0 To dt.Columns.Count - 1
ws.Range("A1").Offset(0, Idx).Value = dt.Columns(Idx).ColumnName
Next
For Idx As Integer = 0 To dt.Rows.Count - 1
' <small>hey! I did not invent this line of code,
' I found it somewhere on CodeProject.</small>
' <small>It works to add the whole row at once, pretty cool huh?</small>
' YES IT'S COOL Brother ...
ws.Range("A2").Offset(Idx).Resize(1, dt.Columns.Count).Value = dt.Rows(Idx).ItemArray
Next
excel.Visible = True
wb.Activate()
Catch ex As Exception
MessageBox.Show("Error accessing Excel: " & ex.ToString())
End Try
End Sub
one way 单程
ArrayList arr = (ArrayList)dataGridView.DataSource;
dt = ArrayListToDataTable(arr);
dataTable2Excel(dt, dataGridView, pFullPath_toExport, nameSheet);
