C# 中 Ilist 轉換成 DataTable

DataTable 數據集靈活好用，開發過程中怎麼把其他類型的數據集轉換成DataTable也就成了很多人想的問題

 

        public DataTable ConvertToDataTable<T>(IList<T> i_objlist)
        {
            if (i_objlist == null || i_objlist.Count <= 0)
            {
                return null;
            }
            DataTable dt = new DataTable(typeof(T).Name);
            DataColumn column;
            DataRow row;
            System.Reflection.PropertyInfo[] myPropertyInfo = typeof(T).GetProperties(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance);
            foreach (T t in i_objlist)
            {
                if (t == null)
                {
                    continue;
                }
                row = dt.NewRow();
                for (int i = 0, j = myPropertyInfo.Length; i < j; i++)
                {
                    System.Reflection.PropertyInfo pi = myPropertyInfo[i];

                    string name = pi.Name;

                    if (dt.Columns[name] == null)
                    {
                        column = new DataColumn(name, pi.PropertyType);
                        dt.Columns.Add(column);
                    }

                    row[name] = pi.GetValue(t, null);
                }
                dt.Rows.Add(row);
            }
            return dt;
        }
