c# different delegate add in dictionary and run deleagate method from dictionary

With C#

I want to my delegate method into one dictionary, and put them all out and run.

for example

class class1{

Func<string,int> method1 = new Func<string,int>( x => 3);
Func<int,double> method2 = new Func<string,int>( x => 3.0);
Func<double,bool> method3 = new Func<string,int>( x => true);

Dictionary<string, dynamic> dic = new Dictionary<string, dynamic>();

dic.add("m1",method1)
dic.add("m2",method2)
dic.add("m3",method3)

// rund all method 

dynamic RunMethod(Dictionary<string, dynamic> dic , dynamic firstInput, int index = 0)
{
  if(index = dic.count) return 
  RunMethod(dic, dic.ElementAt[index].value(input) , index + 1)
}

void main ()
{
 RunMethod( dix , "firstString" )
}
}

(this code has error but expression of what i want to do )

What i want to do is like below.

1. Create Method 1, 2 ,3

2. Output type of Method 1 = Input type of Method2 , Output type of Method 2 = Input type of Method3 Finally get output of Method3

3. There is Run Method that take Input that has type of method1 and method dictionary (or list or something)

4. I want to additional method that check what type of method 1? and output type of method 3
