通过接口c#从不同类型的列表返回结果

public interface IResult<T>
{
    List<T> GetResult();
}

public class StringListResult : IResult<string>
{
    private List<string> _list;

    public StringListResult(List<string> list)
    {
        _list = list;
    }

    public List<string> GetResult()
    {
        return _list;
    }
}

public class IntListResult : IResult<int>
{
    private List<int> _list;

    public IntListResult(List<int> list)
    {
        _list = list;
    }

    public List<int> GetResult()
    {
        return _list;
    }
}

List<string> stringList = new List<string>() { "A", "B", "C" };
IResult<string> stringResult = new StringListResult(stringList);
List<string> result1 = stringResult.GetResult();

List<int> intList = new List<int>() { 1, 2, 3 };
IResult<int> intResult = new IntListResult(intList);
List<int> result2 = intResult.GetResult();
