Dim i As Integer
Dim j As Integer
Dim myFile As New System.IO.StreamWriter(filename)
Dim strTemp As String = ""
For j = 0 To DataGridView1.RowCount - 1
strTemp = ""
For i = 0 To DataGridView1.Columns.Count - 1
strTemp &= "'" & DataGridView1(i, j).Value & "'" & ","
Next
myFile.WriteLine(strTemp)
Next

Answer 1

开头加上
myFile.WriteLine("第一列,第二列,...")

尽量不要大量拼接字符串，这样会很慢，用StringBuilder或者参考早上我给你写的代码
