泛型轉換成dataset的一個方法 直接調用就可以

public static DataSet ConvertToDataSet<T>(IList<T> list)   {   if (list == null || list.Count <= 0)   {   return null;   }   DataSet ds = new DataSet();   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 list)   {   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);   }   ds.Tables.Add(dt);   return ds;   }
