what possible in static class and not in non-static class C#

aarif,

1. first main differnece was mention by you.where public static method are called direclty by class refernce, no need of creating object of class. 

2.  staid methods can call only static method, bit non static can have both.

3. you can mark private method static if there is no reference of global members.

4. class can be marked as static if that is going to used like helper/utilities, such common static methods are used when it called from multiple places. 

5. do not use static method when you are using multi client case where two user calling same static method.  it static values are changed it will be aapplied for all.

6. cases like when you want to use log, you can create singleton instance type of static.

Hi Aarif,

 

A static class is basically the same as a non-static class, but there is one difference a static class cannot be instantiated. In other words, you cannot use the new operator to create a variable of the class type. Because there is no instance variable, you access the members of a static class by using the class name itself. For example, if you have a static class that is named Utility Class that has a public static method named.
