Question

我正在使用此代码将DGV保存到excel文件中：

If ((DataGridView1.Columns.Count = 0) Or (DataGridView1.Rows.Count = 0)) Then
        Exit Sub
    End If

    'Creating dataset to export
    Dim dset As New DataSet
    'add table to dataset
    dset.Tables.Add()
    'add column to that table
    For i As Integer = 0 To DataGridView1.ColumnCount - 1
        dset.Tables(0).Columns.Add(DataGridView1.Columns(i).HeaderText)
    Next
    'add rows to the table
    Dim dr1 As DataRow
    For i As Integer = 0 To DataGridView1.RowCount - 1
        dr1 = dset.Tables(0).NewRow
        For j As Integer = 0 To DataGridView1.Columns.Count - 1
            dr1(j) = DataGridView1.Rows(i).Cells(j).Value

        Next
        dset.Tables(0).Rows.Add(dr1)
    Next

    Dim excel As Microsoft.Office.Interop.Excel.Application
    Dim wBook As Microsoft.Office.Interop.Excel.Workbook
    Dim wSheet As Microsoft.Office.Interop.Excel.Worksheet

    excel = New Microsoft.Office.Interop.Excel.Application
    wBook = excel.Workbooks.Add()
    wSheet = wBook.ActiveSheet()

    Dim dt As System.Data.DataTable = dset.Tables(0)
    Dim dc As System.Data.DataColumn
    Dim dr As System.Data.DataRow
    Dim colIndex As Integer = 0
    Dim rowIndex As Integer = 0

    For Each dc In dt.Columns
        colIndex = colIndex + 1
        excel.Cells(1, colIndex) = dc.ColumnName
    Next

    For Each dr In dt.Rows
        rowIndex = rowIndex + 1
        colIndex = 0
        For Each dc In dt.Columns
            colIndex = colIndex + 1
            excel.Cells(rowIndex + 1, colIndex) = dr(dc.ColumnName)

        Next
    Next

    wSheet.Columns.AutoFit()
    Dim strFileName As String = "D:\ss.xls"
    Dim blnFileOpen As Boolean = False
    Try
        Dim fileTemp As System.IO.FileStream = System.IO.File.OpenWrite(strFileName)
        fileTemp.Close()
    Catch ex As Exception
        blnFileOpen = False
    End Try

    If System.IO.File.Exists(strFileName) Then
        System.IO.File.Delete(strFileName)
    End If

    wBook.SaveAs(strFileName)
    excel.Workbooks.Open(strFileName)
    excel.Visible = True

但是当excel页面显示时，某些数字没有这个点，例如datagridview X = 5.76546753435677但是在excel中它会像X = 576546753435677 你能帮帮我吗？

Answer 1

小数标记在您的软件中可能不同，可能是Excel和这个VB（VB.NET？）环境。默认情况下，Excel使用窗口的区域设置进行数字格式设置（十进制标记和千位分隔符），但您可以覆盖它。同时，如果上述代码在网页中运行，例如，它将使用区域设置进行数字格式设置。我认为两者之间的差异必然导致问题。

这一点在excel
