为什么Image没有显示在名为Image1的GridView和Image控件中?


我的VB代码在下面给出

Why Image is not displaying in GridView and Image control named Image1?


My VB code is given below

Try
            Dim sql As String = "SELECT PHOTO FROM IMAGE WHERE "
            sql += "ID='" & txtID.Text & "'"
            cmd = New OracleCommand(sql, Con)
            ds = New DataSet
            da = New OracleDataAdapter(cmd)

            Try
                If Con.State = ConnectionState.Closed Then
                    Con.Open()
                End If
            Catch ex As Exception
                Response.Write(ex.Message)
                Exit Sub
            End Try
            da.Fill(ds, "IMAGE")
            gvImages.DataSource = ds
            gvImages.DataBind()
            If Con.State = ConnectionState.Open Then
                Con.Close()
            End If


            Dim filepath As String = Server.MapPath(".\App_Data\temp\")
            Dim fullpath As String = filepath & "\"

            If Not (System.IO.Directory.Exists(fullpath)) Then
                System.IO.Directory.CreateDirectory(fullpath)
            End If
            Dim path As String = fullpath & lblblob.Text
            Image1.ImageUrl = path
            
        Catch ex As Exception
            Response.Write(ex.Message)
        End Try

预先感谢您

I appreciate you in advance

推荐答案

更改此行:

Change this line:

gvImages.DataSource = ds

到

to

gvImages.DataSource = ds.Tables(0)

此外，关于路径"，请确保其正确形成.

Further, about ''path'', make sure its correctly formed.
