我有两个功能:
double fullFingerPrinting(string location1, string location2, int nGrams)
double AllSubstrings(string location1, string location2, int nGrams)
我想进入一个循环并依次激活每个函数,并且在每个函数之后我还想打印函数的名称,我该怎么做?
最佳答案
- 定义您的函数通用的委托(delegate)类型。
- 为您的职能创建委托(delegate)集合
- 遍历集合,调用每个委托(delegate)并使用
Delegate.Method
属性以获取方法名称。
示例(经过编辑以显示非静态函数委托(delegate)):
class Program
{
delegate double CommonDelegate(string location1, string location2, int nGrams);
static void Main(string[] args)
{
SomeClass foo = new SomeClass();
var functions = new CommonDelegate[]
{
AllSubstrings,
FullFingerPrinting,
foo.OtherMethod
};
foreach (var function in functions)
{
Console.WriteLine("{0} returned {1}",
function.Method.Name,
function("foo", "bar", 42)
);
}
}
static double AllSubstrings(string location1, string location2, int nGrams)
{
// ...
return 1.0;
}
static double FullFingerPrinting(string location1, string location2, int nGrams)
{
// ...
return 2.0;
}
}
class SomeClass
{
public double OtherMethod(string location1, string location2, int nGrams)
{
// ...
return 3.0;
}
}
