Is there any easy LINQ expression to concatenate my entire List<string> collection items to a single string with a delimiter character?
What if the collection is of custom objects instead of string? Imagine I need to concatenate on object.Name.

You can concatenate a list of strings into a single string with the string method, join() . Call the join() method from 'String to insert' and pass [List of strings] . If you use an empty string '' , [List of strings] is simply concatenated, and if you use a comma , , it makes a comma-delimited string.
In LINQ, the concatenation operation contains only one operator that is known as Concat. It is used to append two same types of sequences or collections and return a new sequence or collection. It does not support query syntax in C# and VB.NET languages. It support method syntax in both C# and VB.NET languages.
The simplest method of adding two strings in C# is using + or += operators.
The Linq All Operator in C# is used to check whether all the elements of a data source satisfy a given condition or not. If all the elements satisfy the condition, then it returns true else return false. There is no overloaded version is available for the All method.
String.Join(delimiter, list); is sufficient.
