wpf Datagrid绑定 Dictionary

数据源格式：Dictionary<int, List<string>>

1.通过xaml设置

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

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