如何绑定到集合的集合以在DataGrid上显示信息？

Question

I'm trying to bind a List<List<string>> to a DataGrid programatically. I'm using this List<List<string>> because the DataGrid has to have a variable number of columns.

Actually, I got to bind the DataGrid to an string[][] but it is partially useful because there will be the need to get this data structure and add rows to it, that's why I want to use a List<List<string>> .

Currently, I'm using this snippet to generate the columns.

dgResults.Columns.Clear();
for (int i = 0; i < numColumns; i++)
{
    DataGridTextColumn textColumn = new DataGridTextColumn();
    textColumn.Binding = new Binding(string.Format("[{0}]", i));
    dgResults.Columns.Add(textColumn);
}

What should I use on textColumn.Binding in order to bind to a List<list<string>> ?

哇...我使用的是string[][]结构...但是使用我编写的代码段， List<List<string>>可以用于预期的目的！
