Question

我正在使用此Linq查询在gridview中显示列。

 protected void Page_Load(object sender, EventArgs e)
 {
    string CS = ConfigurationManager.ConnectionStrings ["ConnectionString"].ConnectionString;
    SqlConnection connection = new SqlConnection(CS);
    SqlCommand command = new SqlCommand();
    SqlDataAdapter adapter = new SqlDataAdapter();
    DataSet ds = new DataSet();
    DataTable dt = new DataTable();
    DataTable dt1 = new DataTable();
    try
    {
        connection.Open();
        command.Connection = connection;
        command.CommandType = CommandType.StoredProcedure;
        command.CommandText = "ManLog_Profits";
        adapter = new SqlDataAdapter(command);
        adapter.Fill(dt);
        adapter.Fill(dt1);
        var query = from r in dt.AsEnumerable()
                    where r.Field<string>("Department") == "Manufacturing"
                    select new
                    {
                        ID = r["ID"].ToString(),
                        Dep_Name = r["Dep Name"].ToString(),
                        Sales_Profit = r["Sales Profit"].ToString(),
                        Sales_Transport = r["Sales Transport"].ToString  (),                            
                    };
        GridView1.DataSource = query;
        GridView1.DataBind();
}
}

现在我怎么可能删除列名的下划线。

Answer 1

在您的linq查询中使用匿名类型。您可以自己决定名称

select new
{
  ID = r["ID"].ToString(),
  DepName = r["Dep Name"].ToString(),
  SalesProfit = r["Sales Profit"].ToString(),
  SalesTransport = r["Sales Transport"].ToString()
};

Answer 2

设置列manualy - AutoGenerateColumns = false：

GridView1.AutoGenerateColumns = false;
GridView1.Columns.Add(new BoundField() { HeaderText = "ID", DataField = "ID" });
GridView1.Columns.Add(new BoundField() { HeaderText = "Dep Name", DataField = "Dep_Name" });
GridView1.Columns.Add(new BoundField() { HeaderText = "Sales Profit", DataField = "Sales_Profit" });
GridView1.Columns.Add(new BoundField() { HeaderText = "Sales Transport", DataField = "Sales_Transport" });

GridView1.DataBind();

您也可以使用DataView.Filter代替Linq查询：

DataView dv = new DataView() {Table = dt};
dv.Filter = "[Department] = 'Manufacturing'"
GridView1.DataSource = dv;
GridView1.DataBind();

删除列名称的下划线
