Can I call class as string param in other class?

Question

Suppose public class A { int a=5; void sum() {int a=5,b=5,c; c=a+b; } } public class B { int b=6; void getmethod( string A,int a ) { //code } } So How can i do it?

Before all, you promise to read this article talking about why cross assembly reference i.e. scenario you mentioned here, is a bad practice. https://stackoverflow.com/questions/10204277/circular-class-references-bad-practice I am continuing here by taking your question as part of a learning practice than a standard to follow. I understood that you need a class name to be passed as a string type rather than an object. If so, below code worked for me in a console application. NB: This is a happy flow and things will change depend on using static types and all. namespace ConsoleApp1 { class Program { static void Main( string [] args) { A a = new A(); a.sum(); Console.ReadLine(); } } public class A { int a = 5; public void sum() { //Getting full classname string className = this .GetType().FullName; B bobj = new B(); bobj.getmethod(className, 10); int a = 5, b = 5, c; c = a + b; } } public class B { int b = 6; public void getmethod( string A, int a) { //Loading and creating the passed class. A Aobj = Assembly.GetExecutingAssembly().CreateInstance(A) as A; Aobj.sum(); } } } Takeaway here is using C# reflection, https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/reflection, you take class names dynamically and also load it dynamically.

@Amit, As u said about public,then i have already tried it ,but not working.

Amit Gupta · Answer

This is because your method is not public, making the access specifier to public will be your expected output

@Amit,As U mention in code that i just create objof Class A But the problem when i will create obj of Class B like : In main Class B obj=new b(); ------------------- obj. getmethod(); --------------------- Then This part will give u error So what Parameter u will pass then in obj. getmethod();

Amit Gupta · Answer

// you can use the class object directly public class B { int b=6; void getmethod(A aClass, int a) { //Use method of aClass here } }

Hi, I want to Use my class A in class B as parameter and also use class A parameter in class b?
