Question

我希望在只选择几个时更改列的名称。
这是我的代码，用于选择列。
现在，我怎样才能更改他们的名字？

        OleDbDataAdapter myadapt = new OleDbDataAdapter(mycommand);
        myadapt.Fill(myset, "Properties");
        DataTable tbSearchResult = myset.Tables["Properties"];
        DataTable tbTemp = new DataTable();

        tbTemp = tbSearchResult.DefaultView.ToTable(true, "DescriptionCities", "DescriptionSurface", "DescriptionBathroom", "DescriptionPrices", "DescriptionRooms", "DescriptionType");

        GridView1.DataSource = tbSearchResult;
        GridView1.DataBind();

Answer 1

这可能会为你做到这一点

string[] selectedColumns = new[] { "DescriptionCities", "DescriptionSurface", "DescriptionBathroom", "DescriptionPrices", "DescriptionRooms", "DescriptionType" };
DataTable dt= new DataView(tbSearchResult).ToTable(false, selectedColumns);

并更改您可以执行的列的名称

dt.Columns["DescriptionCities"].ColumnName = "Cities";

Answer 2

您可以更改sql select语句以仅选择所需的列，并提供标题名称，如下所示

select DescriptionCities as Cities, DescriptionSurface as [Description Surface] from YourTable

仅选择少数时，更改Datagridview中列的名称
