如何使用后面的代码从 wpf C# 中的数据网格中获取所有标题文本

Question

我想从 WPF 应用程序的数据网格中获取所有标题文本。
有没有可能？
我想获取所有标题文本而不仅仅是一个标题文本。我想以集合格式获取所有标题文本。当我们从数据网格中获取项目时。

DataRowView row = (DataRowView)dataGridUserSalesRep.Items.GetItemAt(0);

                        </DataGrid.Columns>

                    </DataGrid>

代码背后：

    private DataTable dataTable;
    MySqlDataAdapter mySqlAdaptor;
    private MySqlCommand cmd;
    MySqlDataReader dataReader;

private void displayDataGrideSalesReport()
        {

        string    con = "SERVER=localhost;PORT=3306;DATABASE=salaamhost;UID=root;PASSWORD='';allow zero datetime=true;SslMode=none";

             var   myconection = new MySqlConnection();
             myconection.ConnectionString = con;
                cmd = myconection.CreateCommand();
                cmd.CommandType = CommandType.Text;



            cmd.CommandText = "SELECT sales.sale_id as id,sales.datetime as date ,sales.cash_sale_client_name as client, users.first_name AS agent , sales.grand_total as sale ,sales.profit  ,sales.currency as curr  FROM sales,users WHERE sales.agent_id = users.user_id group by  sales.sale_id ORDER BY sales.sale_id";

            myconection.Open();
            cmd.ExecuteNonQuery();
            dataTable = new DataTable();
            mySqlAdaptor = new MySqlDataAdapter(cmd);
            mySqlAdaptor.Fill(dataTable);
            dataGridUserSalesRep.ItemsSource = dataTable.AsDataView();
  }

见下图。我想使用后面的代码获取绿色矩形值。

我想获取集合格式的所有标题文本

如果List<string> 对您没问题，您可以在您的代码隐藏中执行此操作：

var HeaderTexts = dataGridUserSalesRep.Columns.Select(e => e.Header.ToString()).ToList();
