在 C# 中创建一个类的语法是什么，它等于 VB.net 中的一个模块

Question

I do almost all of my programming in VB.net (all flavors). I am now been assigned a task to make a new routine in an existing C# application. What I want to be able to do is pass a string variable to a class where I can figure out device type of a symbol handheld and figure out where an executable resides on device. I am trying to keep the class to contain changes we make going forward in one place.

so a brief description is on a screen there will be a button. on that button click I want pass the text of the button to a (what would be a module in VB) a class and depending on text being passed and device type call a separate executable that lives on the device.

Everything I have tried so far has thrown errors. On my button click i have

    String Reponse =   clsCallAction("Activity");

but that gets a message that clsCallAction is a type but is used like a variable.

here is the smaple of clsCallaction

    internal static partial class clsCallAction
     {
public static object GetPath(object lAppName)
{
    string resp = "";
    if (lAppName.Equals("Activity"))

    {
        resp = @"\application\activity.exe";
    }

    return resp;
}
   }

If I put new in front of the clsCallAction("Activity") on button click I get a cannot create instance of the static class 'clsCalACtion'

appreciate any pointers. very new at C#

It would look something like this:

public static class CallAction
{
  public static object GetPath(object lAppName)
  {
    string resp = "";
    if (lAppName.Equals("Activity"))
    {
        resp = @"\application\activity.exe";
    }

    return resp;
  }
}

And would be used like this:

String Reponse =   CallAction.GetPath("Activity");

• Don't prefix classes with cls
• Avoid using object if possible - it just makes everything harder work than it needs to be.. Kinda like calling everything "thing" - ("Put the thing in the thing and open the thing" is harder to understand than "put the key in the lock and open the door")
