No.
The problem is that in C# there are no global variables: every variable is either a local variable or as a part of a class instance.

Local variables only exists as long as the method or code block it is declared as local to is still running - as soon as the ends, the variable is destroyed. This is called scope and it is absolute: once it goes out of scope it no longer exists at all and cannot have a value.

Class variables (called fields) also don't exist in the way you are probably thinking: they ar part of a class instance and don't have a value without the specific instance of the class being referred to in the same way that a glove box only has a content when you talk about a specific car. You can't "list the content of all glove boxes" without unlocking every single car, opening the glove box and having a good rummage about.

So you can't list "all public variables" because they don't exist in isolation in the same way as global variables do in - for example - C.

Instead, use the debugger to look at the class instance, and use that to examine it's properties and fields.

Here is a slightly modified example from C# | Type.GetFields() Method - GeeksforGeeks[^] that lists the public variables from a class:

// C# program to demonstrate the
// Type.GetFields() Method
using System;
// using System.Globalization;
using System.Reflection;

public class GFG {

	// Main Method
	public static void Main()
	{
		// Declaring and initializing object of Type
		Type objType = typeof(Student);

		// try-catch block for handling Exception
		try {

			// Getting array of Fields by
			// using GetField() Method
			FieldInfo[] info = objType.GetFields(BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static);

			// Display the Result
			Console.WriteLine("Fields of current type is as Follows: ");
			for (int i = 0; i < info.Length; i++)
				Console.WriteLine(" {0}", info[i]);
		}

		// catch ArgumentNullException here
		catch (ArgumentNullException e)
		{
			Console.Write("name is null.");
			Console.Write("Exception Thrown: ");
			Console.Write("{0}", e.GetType(), e.Message);
		}
	}
}

// Defining class Student
public class Student
{
	public string Name = "Rahul";
	public string Dept = "Electrical";
	public int Roll = 10;
	public static int id = 02;
}
