How to make method call another one in classes?
C#MethodsCallC# Problem Overview
Now I have two classes allmethods.cs
and caller.cs
.
I have some methods in class allmethods.cs
. I want to write code in caller.cs
in order to call a certain method in the allmethods
class.
Example on code:
public class allmethods
public static void Method1()
{
// Method1
}
public static void Method2()
{
// Method2
}
class caller
{
public static void Main(string[] args)
{
// I want to write a code here to call Method2 for example from allmethods Class
}
}
How can I achieve that?
C# Solutions
Solution 1 - C#
Because the Method2
is static, all you have to do is call like this:
public class AllMethods
{
public static void Method2()
{
// code here
}
}
class Caller
{
public static void Main(string[] args)
{
AllMethods.Method2();
}
}
If they are in different namespaces you will also need to add the namespace of AllMethods
to caller.cs in a using
statement.
If you wanted to call an instance method (non-static), you'd need an instance of the class to call the method on. For example:
public class MyClass
{
public void InstanceMethod()
{
// ...
}
}
public static void Main(string[] args)
{
var instance = new MyClass();
instance.InstanceMethod();
}
Update
As of C# 6, you can now also achieve this with using static
directive to call static methods somewhat more gracefully, for example:
// AllMethods.cs
namespace Some.Namespace
{
public class AllMethods
{
public static void Method2()
{
// code here
}
}
}
// Caller.cs
using static Some.Namespace.AllMethods;
namespace Other.Namespace
{
class Caller
{
public static void Main(string[] args)
{
Method2(); // No need to mention AllMethods here
}
}
}
