When to Use Static Classes in C#

sorry if the question is meaningless or stupid am trying to create a windows service in which i have few class files each class file has some functions that calls another class file.

For example

class file one has a method to create email like

public bool CreateEmail()
{
 try
 {
 //code here
 }
 catch (Exception ex)
 {
    //Write to Log
    to create log  call function from **another class file**
 }
}

and many more calls like this.I would like to know if Using static class is better or creating object for each class and calling the methods will be better.Which is the recommended way?

Answer 1

Ask yourself

• How relevant is this method to your object.
• Does it alter the state of your object in anyway.

If its relevant and does change your object state ,then you should have the method inside the class.If not then you dont need to have that method in your class

In your case from the look of it,its quite clear that its not going to alter any state,rather it needs some information from the other object to send the mail.So i would definitely make this a util class(static class) and use it whenever i need.
