CSV文件中的SQL表将空行显示为“0”&；nbsp&引用；在Excel中

基本上，我在我的VB.NET gridview中显示一个SQL表，一旦它在我的gridview中，我就会有一个按钮将结果从visual studio导出到CSV文件中，CSV文件中的所有内容看起来都很好，除了SQL表中的任何空单元格现在显示为：

  

我尝试使用下面的代码在存储过程中修复此问题：

UPDATE EmailManagementTable
SET Excluded = ''
WHERE Excluded IS NULL

但即使有了这段代码，我仍然会遇到同样的问题

这是将gridview结果导出到CSV的按钮的代码：

    Response.Clear()
    Response.Buffer = True
    Response.AddHeader("content-disposition", "attachment;filename=gvtocsv.csv")
    Response.Charset = ""
    Response.ContentType = "application/text"
    Dim sBuilder As StringBuilder = New System.Text.StringBuilder()
    For index As Integer = 0 To GridView1.Columns.Count - 1
        sBuilder.Append(GridView1.Columns(index).HeaderText + ","c)
    Next
    sBuilder.Append(vbCr & vbLf)
    For i As Integer = 0 To GridView1.Rows.Count - 1
        For k As Integer = 0 To GridView1.HeaderRow.Cells.Count - 1
            sBuilder.Append(GridView1.Rows(i).Cells(k).Text.Replace(",", "") + ",")
        Next
        sBuilder.Append(vbCr & vbLf)
    Next
    Response.Output.Write(sBuilder.ToString())
    Response.Flush()
    Response.[End]()

我想知道我是否能在这方面得到一些帮助

提前谢谢

我解决了我的问题

我在导出按钮中编辑了一些代码，代码如下：

    Response.Clear()
    Response.Buffer = True
    Response.AddHeader("content-disposition", "attachment;filename=gvtocsv.csv")
    Response.Charset = ""
    Response.ContentType = "application/text"
    Dim sBuilder As StringBuilder = New System.Text.StringBuilder()
    For index As Integer = 0 To GridView1.Columns.Count - 1
        sBuilder.Append(GridView1.Columns(index).HeaderText + ","c)
    Next
    sBuilder.Append(vbCr & vbLf)
    For i As Integer = 0 To GridView1.Rows.Count - 1
        For k As Integer = 0 To GridView1.HeaderRow.Cells.Count - 1
            sBuilder.Append(GridView1.Rows(i).Cells(k).Text.Replace(",", "").Replace(" ", "") + ",")
        Next
        sBuilder.Append(vbCr & vbLf)
    Next
    Response.Output.Write(sBuilder.ToString())
    Response.Flush()
    Response.[End]()

问题似乎出在导出数据的按钮后面的代码中。也许你应该发布。不用担心，我已经在问题中发布了VB代码@Nick.McDermaidI在.NET在.asp页面中制作表格时也遇到了这个问题。我能找到的唯一方法就是通过一个循环将它们移除。您可以测试来自GridView的ASCII代码160，然后替换您想要的代码。啊，我明白了，我会尝试一下@JBarker2160谢谢！终于开始工作了。
