Many years me and my friends we were volunteers on my university doing programming classes for young people.

I got main conclusion: Young people are awesome, especially students, because they always bring new and fresh ideas :)
* I loved to do it but my time is limited

  I decided to create something that will help millions of students

int value = int.Parse(text);
Console.WriteLine(value);

2. int.TryParse example

string text = "123";
int value;

if (int.TryParse(text, out value))
	Console.WriteLine(value);

Output:

123

3. Convert.ToInt32 example

string text = "123";
int value = Convert.ToInt32(text);
Console.WriteLine(value);

Output:

123

4. TypeConverter.ConvertFrom example

TypeConverter converter = TypeDescriptor.GetConverter(typeof(int));

string text = "123";
int value = (int)converter.ConvertFrom(text);

Console.WriteLine(value);

Output:

123
