下面是一种转换方式:
[csharp]
class Program
{
static void Main( string[] args)
{
List< object> olist = new List< object>();
olist.Add( new { Name = " Hauk ", Age = 22 });
olist.Add( new { Name = " Emily ", Age = 22 });
// 使用动态类型
foreach (dynamic item in olist)
{
Console.WriteLine(item.Name);
}
// 做类型转换
var obj = ChangeType(olist[ 0], new { Name = "", Age = 0 });
Console.WriteLine(obj.Name);
// 直接反射
Console.WriteLine(olist[ 0].GetType().GetProperty( " Name ").GetValue(olist[ 0]).ToString());
}
static T ChangeType<T>( object obj, T t)
{
return (T)obj;
}
}
/获取所有员工和账号列表对应关系。
DataTable dtAccoutIDList = bll.GetList(model);
//添加一行空行。
DataRow dr = dtAccoutIDList.NewRow();
dr["AccountName"] = "";
dr["AccountID"] = "-2";
dtAccoutIDList.Rows.InsertAt(dr, 0);
dtAccoutIDList.AcceptChanges();
this.cmbAccountList.DisplayMember = "AccountName";
this.cmbAccountList.ValueMember = "[AccountID]";
var query3 = dtAccoutIDList.AsEnumerable().Select(s => new { AccountID = s["AccountID"].ToInt(), AccountName = s["AccountName"].ToString() }).OrderBy(o => o.AccountName).Distinct().ToList();
this.cmbAccountList.DataSource = query3;
--
将数据源转换为匿名对象数组。
var cmbAccountDataSource = this.cmbAccountList.DataSource.ChangeType(new[] { new { AccountID = 0, AccountName = "" } }.ToList());
或者 this.cceAccount.Properties.DataSource = accounts.Select(m => new { Account = m }).ToList();
将选择的项,转换为匿名对象
var cmbSelectedItem = this.cmbAccountList.SelectedItem.ChangeType(new { AccountID = 0, AccountName = "" });
int selectedAccountID=cmbSelectedItem.AccountID
string selectedAccoutName=cmbSelectedItem.AccountName
///扩展方法
public static class Extension
{
public static T ChangeType<T>(this object obj, T t)
{
return (T)obj;
}
}
