Whenever I am debugging a piece of code which involves arrays or lists of ints, doubles, strings, etc/, I prefer printing them over sometimes. What I do for this is write overloaded printArray / printList methods for different types.

for e.g.

I may have these 3 methods for printing arrays of various types

public void printArray(int a);

public void printArray(float b);

public void printArray(String s);

Though this works for me, I still want to know whether it is possible to have a generic method which prints arrays/lists of any types. Can this also be extended to array/list of objects.

There is useful String.Join<T>(string separator, IEnumerable<T> values) method. You can pass array or list or any enumerable collection of any objects since objects will be converted to string by calling .ToString().

int iarr = new int 1, 2, 3;
Console.WriteLine(String.Join("; ", iarr)); // "1; 2; 3"
string sarr = new string "first", "second", "third";
Console.WriteLine(String.Join("n", sarr)); // "firstnsecondnthird"

Arrays and generic lists both implement IEnumerable<T> so just use it as your parameter type.

public void PrintCollection<T>(IEnumerable<T> col)

 foreach(var item in col)
 Console.WriteLine(item); // Replace this with your version of printing

public void printArray<T>(IEnumerable<T> a)
 
 foreach(var i in a)
 
 Console.WriteLine(i);
 

Here's an extension method appropriate for debugging:

[Conditional("DEBUG")]
public static void Print<T>(this IEnumerable<T> collection)

 foreach(T item in collection)
 
 Console.WriteLine(item);
 

you can make a generic method like this

 public static void print<T>(T data)
 
 foreach (T t in data) 
 Console.WriteLine(t.ToString());
