分享如何遍历通过反射的方式获取的集合
通过传来的参数的dbname来用反射动态创建不同类的实体，再调用实体的GetDataByPage方法获取到list集合，请问各位大神该如何遍历集合list啊,代码如下:
private void CreateText(string dbname)
{
Assembly ass = Assembly.LoadFile("C:\\Users\\otsoftadmin\\Documents\\Visual Studio 2010\\Projects\\IndexFactory\\BLL\\bin\\Debug\\IndexFactory.BLL.dll");
Type t = ass.GetType("IndexFactory.BLL." + dbname + "");
MethodInfo mGetDataByPage = t.GetMethod("GetDataByPage");
MethodInfo mGetRecordCount = t.GetMethod("GetRecordCount");
object obj = Activator.CreateInstance(t);
int rowcount=Convert.ToInt32(mGetRecordCount.Invoke(obj,new object[]{""}));
int pagesize = 1000;
int pagecount = Convert.ToInt32(Math.Ceiling(rowcount * 1.0 / pagesize));
string path = @"E:\PatentLunce\new文本\" + dbname + "\\";
if (rowcount / pagesize == 0)
{
for (int i = 1; i <= 1; i++)
{
var list = mGetDataByPage.Invoke(obj, new object[] { i, 1000 });
using (StreamWriter sw = File.CreateText(path + "" + i + ".txt"))
{
Assembly assmodel = Assembly.LoadFile("C:\\Users\\otsoftadmin\\Documents\\Visual Studio 2010\\Projects\\IndexFactory\\Model\\bin\\Debug\\IndexFactory.Model.dll");
Type tm = assmodel.GetType("IndexFactory.Model." + dbname + "");
foreach ( object model in list)
private void CreateText(string dbname)
{
Assembly ass = Assembly.LoadFile("C:\\Users\\otsoftadmin\\Documents\\Visual Studio 2010\\Projects\\IndexFactory\\BLL\\bin\\Debug\\IndexFactory.BLL.dll");
Type t = ass.GetType("IndexFactory.BLL." + dbname + "");
MethodInfo mGetDataByPage = t.GetMethod("GetDataByPage");
MethodInfo mGetRecordCount = t.GetMethod("GetRecordCount");
object obj = Activator.CreateInstance(t);
int rowcount=Convert.ToInt32(mGetRecordCount.Invoke(obj,new object[]{""}));
int pagesize = 1000;
int pagecount = Convert.ToInt32(Math.Ceiling(rowcount * 1.0 / pagesize));
string path = @"E:\PatentLunce\new文本\" + dbname + "\\";
if (rowcount / pagesize == 0)
{
for (int i = 1; i <= 1; i++)
{
var list = mGetDataByPage.Invoke(obj, new object[] { i, 1000 });
using (StreamWriter sw = File.CreateText(path + "" + i + ".txt"))
{
Assembly assmodel = Assembly.LoadFile("C:\\Users\\otsoftadmin\\Documents\\Visual Studio 2010\\Projects\\IndexFactory\\Model\\bin\\Debug\\IndexFactory.Model.dll");
Type tm = assmodel.GetType("IndexFactory.Model." + dbname + "");
foreach ( object model in list)

得到的是List<Model.Asppatent>

如果是list集合你可以参照下面代码
public static List<object> GetRefection(object obj)
{
List<object> objs = new List<object>();
Type t = obj.GetType();
PropertyInfo[] pros = t.GetProperties();
for (int i = 0; i < 2; i++)
{
foreach (PropertyInfo pro in pros)
{
pro.SetValue(obj, i.ToString(), null);
}
objs.Add(obj);
}
return objs;
}凹加凸等于啥 2014-08-26

首先你要先知道IndexFactory这个DLL中执行mGetDataByPage.Invoke(obj, new object[] { i, 1000 });得到的是什么？

多谢，就是这个~~已解决了。

最简单的是用dynamic，连反射都省了
假设obj是你反射得到的list：
object list = ...
foreach (dynamic item in list as IEnumerable)
{
string s = item.Name; // 假设 item 有个属性叫 Name
}

IList MakeListOfType(Type listType)
{
Type type = typeof(List<>);
Type specificListType = type.MakeGenericType(listType);
return (IList)Activator.CreateInstance(specificListType);
}
IList list = MakeListOfType(tm);

遍历的时候转换
形如
foreach (IMachine m in machineList) {
if (m is MachineLine) {
ProcessLine((MachineLine) m);
} else if (m is MachineCircle) {
ProcessLine((MachineCircle) m);
}
}凹加凸等于啥 2014-08-26

反射调用方法只有执行完后才知道数据类型,我现在是没执行之前用var去接获取的数据，然后再遍历他[/quote]
var list = mGetDataByPage.Invoke(obj, new object[] { i, 1000 });
你这不是执行了么？ 你不执行你这list怎么来啊？ 还是你没说清楚

如果你的得到的是List<Model.Asppatent>
那就是
foreach(Model.Asppatent item in list)
