我可以使用带有params关键字的lambda表达式吗?(Can I use a lambda expression with params keyword?)

可以说我有以下代码:

delegate int MyDel (int n);   // my delegate

static int myMethod( MyDel lambda, int n) { 
    n *= n;
    n = lambda(n);
    return n;      // returns modified n
}

这样,具有不同的lambda表达式,我可以调整Method的输出。

myMethod ( x => x + 1, 5);
myMethod ( x => x - 1, 5);

现在,如果我不想在lambda表达式中做任何aritmethic,我可以使用:

myMethod ( x => x, 5);  // and lambda will simply return x

我的问题是,有没有办法使用lambda expresion和'params'可选属性? 也许以某种方式将我的委托嵌入数组中?

 static int myMethod (int n, params MyDel lambda) { 

Lets say I have the following code:

delegate int MyDel (int n);   // my delegate

static int myMethod( MyDel lambda, int n) { 
    n *= n;
    n = lambda(n);
    return n;      // returns modified n
}

This way, having different lambda expression I can tune the output of the Method.

myMethod ( x => x + 1, 5);
myMethod ( x => x - 1, 5);

Now, if I don't want to do any aritmethic in lambda expression, I could use:

myMethod ( x => x, 5);  // and lambda will simply return x

My question is, is there a way to use the lambda expresion with 'params' optional properties? Maybe somehow embedding my delegate in array?

 static int myMethod (int n, params MyDel lambda) {

这有用吗?

编辑对不起,用一只眼睛做这个,让我改一下。

static int myMethod (int n, params  MyDel[] lambdas) {

Does this work?

EDIT Sorry, was doing this with one eye, let me rephrase that.

static int myMethod (int n, params  MyDel[] lambdas) {
