for(int i = 1; i != amount+1; i++)
{
Console.WriteLine("What is the name of the {0} person?", i);
people.Append(Console.ReadLine());
Console.WriteLine("What was their grade?");
grades.Append(Convert.ToDecimal(Console.ReadLine()));
}
(This section is what is affected)
It gets the inputs from the user (I.E. it gets the names and grades, though it doesn't add to the array. I am new to C#, coming from python. Do you guys have any idea how I could fix this issue? TIA

Are you looking for something like this?
using System.Collections.Generic;
int amount = 5;
List<string> people = new List<string>();
List<decimal> grades = new List<decimal>();
for (int i = 0; i < amount; i++)
{
Console.WriteLine("What is the name of the {0} person?", i);
people.Add(Console.ReadLine());
Console.WriteLine("What was their grade?");
grades.Add(Convert.ToDecimal(Console.ReadLine()));
}

I am writing this function, however it gives me: The name 'binarySearchRecursive' does not exist in the current context. I dont understand why i am getting this message, the call is done in the scope of this method itself? Or do i misunderstand a fundamental part of c#?
public static int binarySearchRecusive<T>(T[] a, int low, int high, T v) where T : IComparable
{
if (low < high)
{
var middle = (low + high) / 2;
if (a[middle].CompareTo(v) == 0)
return middle;
if (a[middle].CompareTo(v) < 0)
return binarySearchRecursive(a, low, middle - 1, v);
else
return binarySearchRecursive(a, middle+1, high - 1, v);
}
return -1;
}

Your function goes by this name:
binarySearchRecusive
If you change it to:
binarySearchRecursive
it will work.

Typpo in binarySearchRecusive, instead, try binarySearchRecursive.
If it still don't work then try Program.binarySearchRecursive()

The below code is giving me error "Cannot assign to 'writeline' because it is a 'method group;" at every Console.Writeline statement. I am trying to find out why but I could not find anything to point me in right direction. Any help appreciated.
{
class FizzBuzz
{
static void Main(string[] args)
{
for (int i = 1; i <= 100; i++)
if ((i % 3 == 0) && (i % 5 == 0))
{
Console.WriteLine = "Fizzbuzz" ;
}
else if (i % 3 == 0)
{
Console.WriteLine = "Fizz";
}
else
(i % 5 == 0)
{
Console.WriteLine = "Buzz";
}
System.Console.ReadLine();
}
}
}

You need to set the string in parenthesis:
Console.WriteLine("This string goes to console.");
You tried to assign the method with a value, that is not possible. That works only with properties and fields.

I am new to C#, and need a little help, i know in PHP that i can to something like this
$SelectedEvent="event selected";
if (i > 0)
{
$SelectedEvent = "event";
}
It replace a string easy, but in c# that is not working ok, here is example code i have that is not working
string SelectedEvent = "event selected";
if (i > 0)
{
SelectedEvent = "event";
}
This is not working like in PHP, i can not override the varible?
Here is my example code
EDITED
for (int i = 0; i < Model.Items.Count; i++)
{
string SelectedEvent = "event selected";
if (i > 1)
{
string SelectedEvent = "event";
}
}

You should not redeclare the variable twice but only modify its value:
for (int i = 0; i < Model.Items.Count; i++)
{
string SelectedEvent = "event selected";
if (i > 1)
{
SelectedEvent = "event";
}
// here you can use the SelectedEventVariable
// its value will be "event selected" on the first and second
// iterations and "event" on subsequent
}

Please Correct my code. Please tell me, what is happening here with this code [closed]

The problem, i am facing in this code is that first iteration of loop is good but in second iteration when i press y program gives error.
Error = Input string was not in a correct format.
Line of Error = my = int.Parse(Console.ReadLine());
static void Main(string[] args)
{
int a, my;
char again = 'y';
while ((again == 'y' || again=='Y'))
{
Console.Write("Enter the value for your number = ");
my = int.Parse(Console.ReadLine());
Random b = new Random();
a = b.Next(1, 6);
if (a == my)
{
Console.WriteLine("Congratulations");
}
else
{
Console.WriteLine("you Lost");
Console.WriteLine("My no is {0}.", a);
}
Console.Write("Again? Then press 'y' or 'Y' = ");
again = (char)Console.Read();
}
Console.ReadLine();
}

Change
again = (char)Console.Read();
to
again = (char)Console.ReadLine().First();
Console.Read Reads the next character from the standard input stream. To continue you press a key ('y' in this case) and press 'enter'. Which means you input 2 characters and read 1. Which one is read by next Console.Readline. So, you never get the actual string in this line
my = int.Parse(Console.ReadLine());
Rather you get the character you did not read previously. And this one can not be parsed to integer.

If you got Input string was not in a correct format in a Int32.Parse, try replace it for a Int32.TryParse
Int32.TryParse(Console.ReadLine(), out my);
