泛型 List转换成DataTable

        private DataTable listToDataTable<T>(List<T> ListItem)
        {
            //实列化DataTable对象
            var dt = new DataTable(typeof(T).Name);

            //通过反射获取List实体的属性信息
            PropertyInfo[] propertyInfos = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);

            //给DataTable 添加定义
            foreach (var propertyInfo in propertyInfos)
            {
                dt.Columns.Add(propertyInfo.Name, propertyInfo.PropertyType);
            }

            //给DataTable 添加数据
            foreach (T item in ListItem)
            {
                var values = new object[propertyInfos.Length];
                for (int i = 0; i < propertyInfos.Length; i++)
                {
                    values[i] = propertyInfos[i].GetValue(item);
                }
                dt.Rows.Add(values);
            }

            //返回DataTable
            return dt;
        }
