Question

我试图在txt文件中的一行中输出gridview中的数据，但输出有多行

Dim str As New StringBuilder()

    For i = 0 To RowNo - 1

        str.Append("EDR,")
        str.Append(GridView1.Rows(i).Cells(9).Text)
        str.Append(",")
        str.Append("929110101,")
        str.Append(GridView1.Rows(i).Cells(8).Text)
        str.Append(",")
        str.Append("1,")
        str.Append(System.DateTime.DaysInMonth(Convert.ToInt32(GridView1.Rows(i).Cells(3).Text), Convert.ToInt32(GridView1.Rows(i).Cells(2).Text)))
        str.Append(",")
        str.Append(System.DateTime.DaysInMonth(Convert.ToInt32(GridView1.Rows(i).Cells(3).Text), Convert.ToInt32(GridView1.Rows(i).Cells(2).Text)))
        str.Append(",")
        str.Append(Convert.ToInt32(GridView1.Rows(i).Cells(7).Text))
        str.Append(",")
        str.Append(GridView1.Rows(i).Cells(5).Text)


    Next


    Response.Clear()

    Response.AddHeader("content-disposition", "attachment;filename=test.txt")

    Response.Charset = "ISO-8859-1"

    Response.Cache.SetCacheability(HttpCacheability.NoCache)

    Response.ContentType = "text/plain"

    Dim stringWrite As New System.IO.StringWriter()

    Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)

    Response.Write(str.ToString())

    Response.[End]()

我的输出就像那样

EDR，00000000000000005353291
，929110101,10020108428318
，1,31,31,7397,0

我需要的是

EDR，00000000000000005353291,929110101,10020108428318,1,31,31,7397,0

Answer 1

替换换行符。在VB.NET中，换行符由vbCr，vbLf常量表示。

str= str.Replace(vbCr, "").Replace(vbLf, "")

Answer 2

您是否尝试过清理字符串？

myString = myString.Replace(Environment.NewLine,"")

Response.Write单行输出
