IList,IList<T>转成dataSet

在网上看到的IList转成dataset，下面是源代码和修改后支持泛型IList<T>，测试代码后可用。

public static DataSet ListToDataSet(IList ResList)
{
DataSet RDS = new DataSet();
DataTable TempDT = new DataTable();
System.Reflection.PropertyInfo[] p = ResList[0].GetType().GetProperties();
foreach (System.Reflection.PropertyInfo pi in p)
{
TempDT.Columns.Add(pi.Name, System.Type.GetType(pi.PropertyType.ToString()));
}
for (int i = 0; i < ResList.Count; i++)
{
IList TempList = new ArrayList();
//将IList中的一条记录写入ArrayList
foreach (System.Reflection.PropertyInfo pi in p)
{
object oo = pi.GetValue(ResList[i], null);
TempList.Add(oo);
}

object[] itm = new object[p.Length];
//遍历ArrayList向object[]里放数据
for (int j = 0; j < TempList.Count; j++)
{
itm.SetValue(TempList[j], j);
}
//将object[]的内容放入DataTable
TempDT.LoadDataRow(itm, true);
}
//将DateTable放入DataSet
RDS.Tables.Add(TempDT);
//返回DataSet
return RDS;
}

下面是IList<T>转成dataSet ，好像并没有什么变化呢- -
public DataSet ListToDataSet(IList<object> ResList)
{
DataSet RDS = new DataSet();
DataTable TempDT = new DataTable();
System.Reflection.PropertyInfo[] p = ResList[0].GetType().GetProperties();
foreach (System.Reflection.PropertyInfo pi in p)
{
TempDT.Columns.Add(pi.Name, System.Type.GetType(pi.PropertyType.ToString()));
}
for (int i = 0; i < ResList.Count; i++)
{
IList TempList = new ArrayList();
//将IList中的一条记录写入ArrayList
foreach (System.Reflection.PropertyInfo pi in p)
{
object oo = pi.GetValue(ResList[i], null);
TempList.Add(oo);
}

object[] itm = new object[p.Length];
//遍历ArrayList向object[]里放数据
for (int j = 0; j < TempList.Count; j++)
{
itm.SetValue(TempList[j], j);
}
//将object[]的内容放入DataTable
TempDT.LoadDataRow(itm, true);
}
//将DateTable放入DataSet
RDS.Tables.Add(TempDT);
//返回DataSet
return RDS;
}
