<\/span><\/h2>\nThe FirstOrDefault<\/code> method in LINQ is commonly used to get the first element from a collection that satisfies a specified condition. It returns the default value of the type if no matching element is found. However, when used without any condition, it simply returns the first element of the collection. Here’s an example:<\/p>\n“`csharp
\nvar numbers = new List { 1, 2, 3, 4, 5 };
\nint firstNumber = numbers.FirstOrDefault();
\n“`<\/p>\nThe FirstOrDefault<\/code> method can be used to retrieve a single value from a LINQ query by selecting the desired column or property from the result.<\/strong> For instance, if you have a collection of objects with a property called Name<\/code> and you want to retrieve the first name, you can modify the query like this:<\/p>\n“`csharp
\nvar names = new List { … }; \/\/ Assume a collection of Person objects with a ‘Name’ property
\nstring firstName = names.Select(p => p.Name).FirstOrDefault();
\n“`<\/p>\n
