Using Implicit Method Group Conversion in C#

Its great to learn something everyday that keeps me updated in .NET which always makes me feel fresh . With every topic that i come across everyday , it make me feel that i am still a fresher .

Today , i got to know something about Implicit Method Group Conversion in C# .

Well , if you are still looking to know whet it is , the example below will clearly explain you this .

Assume that the List contains the Names Senthil Kumar,Developer,Trivium like below.

List<string> LstNames = new List<string>();

LstNames.Add("Senthil Kumar");

LstNames.Add("Developer");

LstNames.Add("Trivium");

How will you display the Names in the list ?

Most Developers (including me ) will end up doing something like this .

foreach (string str in LstNames)
{

     Console.WriteLine(str);

}

or

for (int i = 0; i < LstNames.Count ; i++)
{

     Console.WriteLine(LstNames[i]);

}

Now , the same can be achieved with just one line of code .

LstNames.ForEach(str => Console.WriteLine(str));

Further , i can remove the lambda expression and display the same names with the Implicit Method Group Conversion like below

LstNames.ForEach(Console.WriteLine);

This results in the same output as the one as above  .

List<string> LstNames = new List<string>();

LstNames.Add("Senthil Kumar");

LstNames.Add("Developer");

LstNames.Add("Trivium");

LstNames.ForEach(Console.WriteLine);
