Question

1.00/5 (2 votes)

See more:

In the main method of a C# console application usually we use string as parameter (

C#

static void Main(string[] args)

)
Can we use other types such as Integer as parameter of main method. Besides can we use more than one parameter is main method?

What I have tried:

static void Main(int[] args){
}

You can only have string type parameters, it is your task to convert strings as you need.
A simple space is needed to separate parameters.

Do you understand the purpose of command line; and why it's represented in array of strings, to your application?

It's done by historical reasons, because a string is a universal way to pass data. This is what it is, you cannot change it.

In practice "other types" means string using string (or strings) but trying to parse it according some application schema.

Please see my article where I present an easy-to-use facility of this kind: Enumeration-based Command Line Utility[^].

Another alternative, also a CodeProject work, is referenced in my article.

You can have as many parameters to Main as you like, that is why it is defined as a string[] rather than string.

Although all of the arguments are passed into Main as strings, they can be converted to other types. See the reference Command-Line Arguments (C# Programming Guide)[^]

Pass path to image as argument and load image in code.

5ed, but the request still makes practical sense, if it's reformulated accurately. Please see Solution 2.
