如何使用c＃在DataGrid（WPF）中显示列表列表 [英] How to display a list of list in DataGrid( WPF) using c#

问题描述

我有一个标题（列）列表，然后是数据行，并希望通过两种方式在DataGrid中显示它

I have a List of headers(columns) and then rows of data and want to show it in DataGrid with two way bindings

List<string> headers = new List<string> { "FirstName", "LastName", "Age" };
List<string> row1 = new List<string> { "John", "Doe", "19" };
List<string> row2 = new List<string> { "Jane", "Doe", "21" };
List<string> row3 = new List<string> { "Suzie", "Q", "52" };
List<string> row4 = new List<string> { "No", "Body", "48" };

List<List<string>> tableValues =
 new List<List<string>> { row1, row2, row3, row4 };

编辑器不允许我显示列表列表，因为它具有多个<

The editor does not let me show List of List since it has multiple <

我非常感谢您。

推荐答案

鉴于标头的数量可能有所不同，我建议转换为便于双向数据绑定的格式的数据并使用DataTable：

given that number of headers may vary, I suggest to tranform data in the format convenient for two-way data binding and use DataTable:

var dt = new DataTable();

// create columns and headers
int columnCount = headers.Count;
for (int i = 0; i < columnCount; i++)
    dt.Columns.Add(headers[i]);

// copy rows data
for (int i = 0; i < tableValues.Count; i++)
    dt.Rows.Add(tableValues[i].Take(columnCount).ToArray());

// display in a DataGrid
dataGrid.ItemsSource = dt.DefaultView;
