Int32 represents a 32-bit signed integer. To represent it as a string, use the ToString() method.Firstly, declare and initialize an Int32 variable.int val = 1023;Now, represent it as a string.val.ToString()Let us see the complete example.Example Live Demousing System; class Demo {    static void Main() {       int val ...

This method is used to handle empty collections. Instead of showing an error, this method displays a default value.We have the following list.List myList = new List();As you can see, since the above list is empty, we can display the default value.var res = myList.DefaultIfEmpty();Let us see an example.Example Live Demousing ...
