List of 8 C# Interview Questions <\/strong><\/span><\/h2>\n\n\n\n

1. How would you implement the Singleton design pattern in C#?<\/strong><\/h3>\n\n\n\n

There are numerous ways to implement Singleton in C#: <\/span>

\u2022 Standard Singleton Implementation <\/span>
\u2022 Early Instance Creation <\/span>
\u2022 Double Checked Locking <\/span>
\u2022 Using Generics <\/span>
\u2022 Fully Lazy Instantiation <\/span>
\u2022 Using Lazy type <\/span><\/p>\n\n\n\n

2. Describe the Async method of C#?<\/strong><\/h3>\n\n\n\n

Async (asynchronous programming) can be described as a method that returns to the calling method before finishing its work fully. It then proceeds to complete its work while the calling method goes along with its execution. <\/span><\/p>\n\n\n\n

3. What is an Object?<\/strong><\/h3>\n\n\n\n

An object is an instance of a class and comprises of real values as opposed to variables. For instance, say we were to create an instance of the class Employee called \u201cRaj\u201d. <\/span>
Employee Raj = new Employee(); <\/span>
We will now be able to access all the methods in the class \u201cEmployee\u201d via object \u201cRaj\u201d as given below. <\/span>
Raj.setName(\u201cXYZ\u201d); <\/span><\/p>\n\n\n\n

4. Is it possible to serialise hashtables?<\/strong><\/h3>\n\n\n\n

It is not possible to serialise hashtables \u2013 a collection of key-value pairs \u2013 as the .NET Framework prevents serialisation of any object that implements the IDictionary interface. The XmlSerializer class will display an error when an attempt is made to serialise a Hashtable. <\/span><\/p>\n\n\n\n

5. Explain the differences between \u201cout\u201d and \u201cref\u201d parameters in C#?<\/strong><\/h3>\n\n\n\n

Although quite similar, the “out” parameter can be passed to a method and doesn’t require to be initialised whereas the “ref” parameter has to be initialised and set to something before it is used. <\/span><\/p>\n\n\n\n

6. Can you explain the concept of inner exception in C#?<\/strong><\/h3>\n\n\n\n

An inner exception can be described as a property of exception class which gives you a brief understanding of the exception, i.e., details on the parent exception as well as the child exception. <\/span>
<\/span><\/span><\/span><\/p>\n\n\n\n

7. Explain the use of the System. Environment class in C#.NET.<\/strong><\/h3>\n\n\n\n

The System. Environment class provides all relevant information about the current environment and platform. It can also be used to retrieve information such as: <\/span><\/p>\n\n\n\n

a. Command-line arguments <\/span>
b. The exit code <\/span>
c. Environment variable settings <\/span>
d. Contents of the call stack <\/span>
e. Time since last system boot <\/span>
f. The version of the common language runtime <\/span><\/p>\n\n\n\n

Further, if you\u2019re looking to retrieve environment variable settings, version of the common language runtime, etc., the System, environment class can help you do so. <\/span><\/p>\n\n\n\n

8. Explain what is Namespaces in C#.<\/strong><\/h3>\n\n\n\n

In <\/span>C#<\/span><\/a><\/strong>, Namespaces are usually used to organise and provide a level of separation of codes. Indicated by the keyword \u201cnamespace,\u201d they can also be put to use to compose substantial code ventures. <\/span><\/p>\n\n\n\n
