C# 0 The Complete Reference

MinVal( )

 is called, the arguments are passed to it via the 

nums

 array. The length 

of the array equals the number of elements. Thus, you can use 

MinVal( )

 to find the minimum 

of any number of values.

Notice the last call to 

MinVal( )

. Rather than being passed the values individually, it is 

passed an array containing the values. This is perfectly legal. When a 

params

 parameter 

is created, it will accept either a variable-length list of arguments or an array containing the 

arguments.

Although you can pass a 

params

 parameter any number of arguments, they all must 

be of a type compatible with the array type specified by the parameter. For example, calling 

MinVal( )

 like this:

min = ob.MinVal(1, 2.2); // Wrong!

is illegal because there is no automatic conversion from
