如何将一维字符串数组结果绑定到数据网格列标头

我有一个如下的查询，它返回服务器名称和组件名称的列表

string match = "TEST"
var headerArray = from a in this.db.Servers
                 where a.ServerID.Contains(match)
                 join b in this.db.Components
                        on a.ServerID equals b.ServerID into g
                select new
                {
                    a.ServerID,
                    Components = g.Select(x => x.Name), 
                };
List<string> result = new List<string>();
foreach (var server in headerArray)
{
    result.Add(server.ServerID);
    foreach (var componentName in server.Components)
        result.Add(componentName);
}
string[] header = result.ToArray();

编辑

datagrid1.ItemsSource = header.ToList();

header以数组的形式存储服务器名列表。如何将此结果绑定到数据网格列?
