DataGridView数据导出到Excel或者Word
谁能给个Vb.net下DataGridView数据导出到Excel或者Word的例子？

[解决办法]
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
Dim dsEmployeeContract As DataSet = New DataSet
dsEmployeeContract.Clear()
dsEmployeeContract = ds

If dsEmployeeContract Is Nothing Then
MsgBox("没有数据，无法导出！", MsgBoxStyle.OKOnly)
Exit Sub
Else
Dim xlsapp As New Excel.Application
xlsapp.Workbooks.Add()
xlsapp.Visible = True
xlsapp.Range(xlsapp.Cells(1, 1), xlsapp.Cells(1, dsEmployeeContract.Tables(0).Columns.Count)).Select()
xlsapp.Selection.Merge()
xlsapp.Range(xlsapp.Cells(1, 1), xlsapp.Cells(1, 1)).Font.Size = 15
xlsapp.Range(xlsapp.Cells(1, 1), xlsapp.Cells(1, dsEmployeeContract.Tables(0).Columns.Count)).Font.Bold = True
Dim i As Int16
For i = 1 To dsEmployeeContract.Tables(0).Columns.Count
xlsapp.Cells(2, i) = dsEmployeeContract.Tables(0).Columns(i - 1).ColumnName
Next
Dim rowindex As Integer = 3
Dim colindex As Integer
Dim col As DataColumn
Dim row As DataRow
Dim nxh As Integer = 1
For Each row In dsEmployeeContract.Tables(0).Rows
colindex = 1
For Each col In dsEmployeeContract.Tables(0).Columns
If colindex = 1 Then
xlsapp.Cells(rowindex, colindex) = RTrim(Convert.ToString(row(col.ColumnName)))
Else
xlsapp.Cells(rowindex, colindex) = RTrim(Convert.ToString(row(col.ColumnName)))
End If
colindex += 1
Next
rowindex += 1
nxh += 1
Next
xlsapp.Columns.AutoFit()
End If
Catch ex As Exception
MsgBox(Err.Description, MsgBoxStyle.Critical)
End Try
End Sub
ds为Public ds As DataSet = New DataSet，是你DataGridView数据
