vb.net - vb.net linq导致datagridview选择更改列顺序

Question

我的问题是dtJoin结果datagrid与选择查询列顺序不同。

它Address先显示字段，然后ClientCd再ClientName显示MemberCd

我不知道它按列名顺序显示结果的原因？

我的代码是

Dim dtClient As DataTable
dtClient = getDataTable_sql(SqlStr, SQLCnn)
dtJoin = (From C In dtClient Select C!MemberCd, C!ClientCd, C!Address, C!ClientName).ToList
DataGridView1.DataSource = dtJoin

请任何人帮助我

在重新加载数据源之前设置为DataSource。DataGridView1Nothing

Dim dtClient As DataTable
dtClient = getDataTable_sql(SqlStr, SQLCnn)
dtJoin = (From C In dtClient Select C!MemberCd, C!ClientCd, C!Address, C!ClientName).ToList
'-------------------
DataGridView1.DataSource = Nothing
'-------------------
DataGridView1.DataSource = dtJoin
