How Can I Efficiently Convert a C# List to a String?

Converting List to String in C#

When working with string representations of collections, the toString method of a List object may return the name of the underlying object rather than the desired string of elements. To overcome this, consider the following approaches:

Using String.Join()

Utilize the String.Join() method to concatenate the elements of the list into a single string. The separator argument specifies the delimiter between elements:

string combinedString = string.Join(",", myList.ToArray());

Shorthand Syntax

Alternatively, you can directly pass the list to String.Join() with the preferred separator:

string combinedString = string.Join(",", myList);

Reference

Refer to the Join(String, IEnumerable) method documentation for more information on how it combines strings from a collection.
