如何将linq查询的结果 转换为DataTable,最简单的实现方法

public static DataTable CopyToDataTable<T>(this IEnumerable<T> array)
{
var ret = new DataTable();
foreach (PropertyDescriptor dp in TypeDescriptor.GetProperties(typeof(T)))
ret.Columns.Add(dp.Name, dp.PropertyType);
foreach (T item in array)
{
var Row = ret.NewRow();
foreach (PropertyDescriptor dp in TypeDescriptor.GetProperties(typeof(T)))
Row[dp.Name] = dp.GetValue(item);
ret.Rows.Add(Row);
}
return ret;
}
记得添加引用空间
