动态传递参数 [英] Pass parameter dynamically
问题描述
我必须将列表传递给下面的函数。
public static 列表< List< T>> AllCombinationsOf< T>( params List< T> [] sets)
{
// 这里的一些代码
}
现在我通过使用以下方法调用该函数:
var x = AllCombinationsOf(A,B,C);
我不知道运行前需要传递的列表数量。它会动态变化。如何动态创建列表并传递此函数。
如果我想将参数传递给AllCombinationsOf为
AllCombinationsOf(A,B,C ,d);
AllCombinationsOf(A,B);
AllCombinationsOf(A,B,C,D,E);
意味着我必须做什么?
我必须动态传递参数(将要更改的参数)
我试图将列表添加到此
列表与LT;列表与LT;串GT;> lst = new 列表< List<字符串>>();
但它不起作用
您只需列出值:
List< string> l1 = new 列表< string> { heelo, 再见};
List< string> l2 = new 列表< string> { heelo, 再见};
List< int> l3 = new List< int> { 1 , 2 , 3 ,< span class =code-digit> 4 };
var x = AllCombinationsOf(l1,l2);
...
public static 列表< List< T> ;> AllCombinationsOf< T>( params List< T> [] sets)
{
Console.WriteLine(sets.Length);
return sets.ToList();
}
显然,你不能将第三个列表添加到参数中,但如果只列出你的参数,它们将作为List-of-列表传递字符串
I have to pass the list to below function.
public static List<List<T>> AllCombinationsOf<T>(params List<T>[] sets)
{
//some set of code here
}
Now I call the function by using:
var x = AllCombinationsOf(A,B,C);
I don't know the number of list that I need to pass before runtime. It will be change dynamically. How to I create the list dynamically and pass this function.
If I want to pass parameter to "AllCombinationsOf" as
AllCombinationsOf(A,B,C,D);
AllCombinationsOf(A,B);
AllCombinationsOf(A,B,C,D,E);
means what I have to do?
I have to pass parameter as dynamically( parameter that will be change)
I tried to add list into this
List<List<string>> lst = new List<List<string>>();
but it not working
You just list the values:
List<string> l1 = new List<string> { "heelo", "goodbye" }; List<string> l2 = new List<string> { "heelo", "goodbye" }; List<int> l3 = new List<int> { 1, 2, 3, 4 }; var x = AllCombinationsOf(l1, l2); ... public static List<List<T>> AllCombinationsOf<T>(params List<T>[] sets) { Console.WriteLine(sets.Length); return sets.ToList(); }Obviously, you can't add the third list into the parameters, but if you just list your params, they will be passed as an array of List-of-strings
