推荐答案

委托是一个对象。只要创建了预期的委托，你通常会，并把它传递的参数数组中为止。这是一个虚构的例子：

A delegate is an object. Just create the expected delegate as you would normally, and pass it in the parameters array. Here is a rather contrived example:

class Mathematician {
	public delegate int MathMethod(int a, int b);

	public int DoMaths(int a, int b, MathMethod mathMethod) {
		return mathMethod(a, b);
	}
}

[Test]
public void Test() {
	var math = new Mathematician();
	Mathematician.MathMethod addition = (a, b) => a + b;
	var method = typeof(Mathematician).GetMethod("DoMaths");
	var result = method.Invoke(math, new object[] { 1, 2, addition });
	Assert.AreEqual(3, result);
}
