C# Stuck understanding Array?

[MRR]

What is the following code doing?

string result = new string (new char[])
{
'Profile_unknown'
});

Can you explain what the following code is and what it is actually doing? line by line Please



the next one as well

new string(new char[]
{
'tdata'
}

Never post screenshots of code. Post the code itself.
Where did you find this silly piece of code anyway ?

What is the following code

string result = new string (new char[])
{
'Profile_unknown'
});

Generating compiler errors is what it's doing. It's illegal in C# to put more than one character between ' '. It's also not permitted to declare an array without a size ir initializer

Think of it this way.

string username = "ABCDEFG";
char[] userNameArray = new char[] {'A','B','C','D','E','F','G'};

//Look at the username almost like an array of chars (characters).
//Now, display both the username and the char array...what do you get?
Console.WriteLine($"The string of username = {username}");
Console.WriteLine();
Console.WriteLine("And the value of the userNameArray is:");
userNameArray.Dump();
Console.WriteLine("Which printed out is:");
Console.WriteLine(userNameArray);
/*
    You can reference a specific index of the string, which is a single char.
    You can't have a whole line of letters make up one letter :)

    Example - if I want to pick out the single letter 'D' above alone, I can look for that index of the string...which is a single character.
*/
Console.WriteLine();
Console.WriteLine($"Getting the letter {username[3]} here...");
