您可使用您职能参数的重字或关键词。

int i;
int j;

dosomething(out i, out j);    

public void dosomething(out int a, out int b)
{
   a = 1;
   b = 2;
}

Answer 4

界定新的数据类型,其产出如下:

public class Output
{
    public object Val1 { get; set; }
    public object Val2 { get; set; }
}

并返还新的类别产出:

public Output FunName()
{
     Output out = new Output;
     out.Val1 = val1;
     out.Val2 = val2;
     return out;
}
