Writing information from Combo-box to text file
我无法弄清楚如何在每次参赛后添加空格
例如
约翰 玛丽 乔
而不是
John_ 玛丽_ 乔_
如何填写条目
有问题的代码
Dim sb as new StringBuilder()
For Each item As Object In cmbworld.Items
'Dim test As String
'test = item
sb.AppendFormat("{0} {1}", item, Environment.NewLine)
Next
Dim FILE_NAME As String = "D:\Documents\test.txt"
If System.IO.File.Exists(FILE_NAME) = True Then
Dim objWriter As New System.IO.StreamWriter(FILE_NAME)
objWriter.Write(sb.ToString()) 'Use the stringbuilder here
objWriter.WriteLine()
objWriter.Close()
MsgBox("Text written to file")
Else
MsgBox("File Does Not Exist")
End If
答案 0 :(得分:1)
删除此处的空格:
sb.AppendFormat("{0} {1}", item, Environment.NewLine)
所以你有:
sb.AppendFormat("{0}{1}", item, Environment.NewLine)
