原文网址： https://www.cnblogs.com/zany-hui/articles/7623874.html

数据源格式：Dictionary<int, List<string>>

1.通过xaml设置

1  <DataGrid x:Name="dg" ItemsSource="{Binding Dic}" AutoGenerateColumns="False">
2             <DataGrid.Columns>
3                 <DataGridTextColumn Header="id" Binding="{Binding Key}"/>
4                 <DataGridTextColumn Header="Name" Binding="{Binding Value[0]}"/>
5                 <DataGridTextColumn Header="Name" Binding="{Binding Value[1]}"/>
6                 <DataGridTextColumn Header="Name" Binding="{Binding Value[2]}"/>
7             </DataGrid.Columns>
8         </DataGrid>

2.通过代码设置

DataGridTextColumn column = new DataGridTextColumn();
column.Header = "name4";
column.Binding = new Binding("Value[3]");
dg.Columns.Add(column);

<DataGrid x:Name="dg" ItemsSource="{Binding Dic}" AutoGenerateColumns="False">
    <DataGrid.Columns>
      <DataGridTextColumn Header="id" Binding="{Binding Key}"/>
    </DataGrid.Columns>
</DataGrid>
 
 
 private Dictionary<int, List<string>> dic;
 
 public Dictionary<int, List<string>> Dic
 {
     get { return dic; }
     set { dic = value; }
 }
 
 public MainWindow()
 {
     InitializeComponent();
     this.DataContext = this;
     Dic = new Dictionary<int, List<string>>();
     Dic.Add(1, new List<string> { "a", "b", "c", "5" });
     Dic.Add(2, new List<string> { "d" });
     Dic.Add(3, new List<string> { "e", "f" });
 
     int count = 0;
     foreach (List<string> lst in Dic.Values)
     {
         if (lst.Count > count)
         {
 
             for (int i = count; i < lst.Count; i++)
             {
                 DataGridTextColumn column = new DataGridTextColumn();
                 column.Header = "name" + i;
                 column.Binding = new Binding(string.Format("Value[{0}]", i));
                 dg.Columns.Add(column);
             }
             count = lst.Count;
         }
     }
 }
