I'm just curious as to whether there is something built into either the C# language or the .NET Framework that tests to see if something is an integer
if (x is an int) // Do something
It seems to me that there might be, but I am only a first-year programming student, so I don't know.
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr.
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
C is more difficult to learn than JavaScript, but it's a valuable skill to have because most programming languages are actually implemented in C. This is because C is a “machine-level” language. So learning it will teach you how a computer works and will actually make learning new languages in the future easier.
Use the int.TryParse method.
string x = "42"; if(int.TryParse(x, out int value)) // Do something
If it successfully parses it will return true, and the out result will have its value as an integer.
If you just want to check type of passed variable, you could probably use:
var a = 2; if (a is int) { //is integer } //or: if (a.GetType() == typeof(int)) { //is integer }
