--  TrimStart和Replace为什么不起作用

Dim tb As Table = e.Form.Controls("tblDtl").Table
Dim ziduan As String
ziduan = ""
For Each c As Col In tb.Cols
ziduan = ziduan & "," & c.Name
Next
ziduan.TrimStart(",")
ziduan.Replace("应付工资","")
Dim tx As WinForm.TextBox = e.Form.Controls("TextBox1")
tx.Text = ziduan
想得到表的所有字段名称，然后去掉不需要的字符，但是运行代码后得到的字符串“ziduan”中第一个逗号和“应付工资”几个字都没有去掉
