[英]Abstract function have dynamic return type - C#
I am trying to have an abstract function return a List of a custom data type during run time. 我正在尝试让抽象函数在运行时返回自定义数据类型的列表。
//Abstract class: Integr //抽象类:Integr
abstract public List < object > getRefills();
//Implementation in derived class: TMTStandard //在派生类中的实现:TMTStandard
public override List < TMTStandardRefill > getRefills()
{
List<TMTStandardRefill> refills = db.TMTStandarRefills.ToList();
return refills;
}
//I call the function to bind my data to a gridview data source //我调用函数将我的数据绑定到gridview数据源
dataGridView1.DataSource = integr.getRefills();
Any help would be appreciated. 任何帮助,将不胜感激。 I have looked at Generics but was unable to come up with a solution. 我看过泛型,但无法提出解决方案。
Make Integr
a generic of T
: 使Integr
为T
的泛型:
public abstract class Integr<T>
{
public abstract IList<T> GetRefills();
}
public class TMTStandard : Integr<TMTStandardRefill>
{
public override IList<TMTStandardRefill> GetRefills()
{
// ...
}
}
