这是我的代码你能不能请帮助我。
here is my code Can you please help me.
Private Sub ExportingEdited()
If ((DataGridView1.Columns.Count = 0) Or (DataGridView1.Rows.Count = 0)) Then
Exit Sub
End If
Dim columnCollection As DataGridViewColumnCollection = DataGridView1.Columns
Dim currentVisibleColumn As DataGridViewColumn = columnCollection.GetFirstColumn(DataGridViewElementStates.Visible)
Dim lastColumnExported As DataGridViewColumn = currentVisibleColumn
Dim visibleColumnCount As Integer = columnCollection.GetColumnCount(DataGridViewElementStates.Visible)
Dim xlApp As Microsoft.Office.Interop.Excel.Application
Dim xlWorkBook As Microsoft.Office.Interop.Excel.Workbook
Dim xlWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
Dim misValue As Object = System.Reflection.Missing.Value
xlApp = New Microsoft.Office.Interop.Excel.Application With {.Visible = True}
xlWorkBook = xlApp.Workbooks.Add(xlPath)
xlWorkSheet = CType(xlWorkBook.Sheets("sheet1"), Microsoft.Office.Interop.Excel.Worksheet)
For r = 0 To DataGridView1.Rows.Count - 1
'Reset values'
currentVisibleColumn = columnCollection.GetFirstColumn(DataGridViewElementStates.Visible)
lastColumnExported = currentVisibleColumn
For c = 2 To visibleColumnCount + 1
Dim value = DataGridView1.Rows(r).Cells(currentVisibleColumn.Index).Value
If value IsNot vbNullString Then
xlWorkSheet.Cells(r + 58, c) = value.ToString()
End If
currentVisibleColumn = columnCollection.GetNextColumn(lastColumnExported, DataGridViewElementStates.Visible, DataGridViewElementStates.None)
lastColumnExported = currentVisibleColumn
Next
Next
xlWorkSheet.SaveAs(CType(xlPath, String))
xlWorkBook.Close()
xlApp.Quit()
releaseObject(xlApp)
releaseObject(xlWorkBook)
releaseObject(xlWorkSheet)
Dim p As ProcessStartInfo = New ProcessStartInfo(CType(xlPath, String))
Process.Start(p)
End Sub
我尝试了什么：
我试过这个
What I have tried:
I tried this
Private Sub ExportingEditedspecificrow()
If ((DataGridView1.Columns.Count = 0) Or (DataGridView1.Rows.Count = 0)) Then
Exit Sub
End If
Dim columnCollection As DataGridViewColumnCollection = DataGridView1.Columns
Dim currentVisibleColumn As DataGridViewColumn = columnCollection.GetFirstColumn(DataGridViewElementStates.Visible)
Dim lastColumnExported As DataGridViewColumn = currentVisibleColumn
Dim visibleColumnCount As Integer = columnCollection.GetColumnCount(DataGridViewElementStates.Visible)
Dim xlApp As Microsoft.Office.Interop.Excel.Application
Dim xlWorkBook As Microsoft.Office.Interop.Excel.Workbook
Dim xlWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
Dim misValue As Object = System.Reflection.Missing.Value
xlApp = New Microsoft.Office.Interop.Excel.Application With {.Visible = True}
xlWorkBook = xlApp.Workbooks.Add(xlPath)
xlWorkSheet = CType(xlWorkBook.Sheets("sheet2"), Microsoft.Office.Interop.Excel.Worksheet)
For r = 0 To DataGridView1.Rows.Count - 1
'Reset values'
currentVisibleColumn = columnCollection.GetFirstColumn(DataGridViewElementStates.Visible)
lastColumnExported = currentVisibleColumn
For c = 2 To visibleColumnCount + 1
Dim value = DataGridView1.Rows(r).Cells(currentVisibleColumn.Index).Value
If value IsNot vbNullString Then
xlWorkSheet.Cells(r + 58, c) = value.ToString()
If c = 7 Then
For a = 0 To DataGridView1.Rows.Count - 1
'Reset values'
currentVisibleColumn = columnCollection.GetFirstColumn(DataGridViewElementStates.Visible)
lastColumnExported = currentVisibleColumn
For b = 2 To visibleColumnCount + 1
value = DataGridView1.Rows(a).Cells(currentVisibleColumn.Index).Value
If value IsNot vbNullString Then
xlWorkSheet.Cells(a + 67, b) = value.ToString()
End If
Next
Next
End If
End If
currentVisibleColumn = columnCollection.GetNextColumn(lastColumnExported, DataGridViewElementStates.Visible, DataGridViewElementStates.None)
lastColumnExported = currentVisibleColumn
Next
Next
xlWorkSheet.SaveAs(CType(xlPath, String))
xlWorkBook.Close()
xlApp.Quit()
releaseObject(xlApp)
releaseObject(xlWorkBook)
releaseObject(xlWorkSheet)
Dim p As ProcessStartInfo = New ProcessStartInfo(CType(xlPath, String))
Process.Start(p)
End Sub
但结果是这样的结果
but what happen is the result became like this
|___A__|___B_____|____C___|__D____|___E___|_________F___________|
_
1 I want to go out inside my house
_
2 He want to go out From his School
_
3

4 I I I I I I
_
5 I I I I I I

推荐答案
肯定会更好地将源数据转换为正确的格式，然后所有代码都需要将数据输出到Excel中。在事实结束之后弄乱了数据并且容易出错。
Surely it would be better to get the source data into the correct format, then all your code needs to do it output the data into Excel. Messing around with the data after the fact is over complicating things and error prone.
