C # functions and usage of param

If a large number of parameters are required in a method, you can use Param to integrate these parameters into an array.

For example:

 
Int add (int A, int B, int C, int D ,......)
 

 
{
 

 
Return A + B + C + D + ......;
 

 
}
 

 
You will find it better to change the parameter to an array.
 

Int add (INT [] ARGs)
 

 
{
 

 
Int sum = 0;
 

 
Foreach (INT number in ARGs)
 

 
{
 

 
Sum + = number;
 

 
}
 

 
Return sum;
 

}
 

 
But it is inconvenient to use. If you want to use add (1, 2), you have to put 1, 2 in the array.
 

 
Int [] array = new int {1, 2 };
 

 
In this case, you can add Params to the above method.
 

 
Int add (Params int [] ARGs ){......}
 

 
Then, you only need to add (1, 2), add (7, 8, 9, 10, 12 )......
