How to convert IQueryable<string> to string in C#?

If you have an IQueryable<string> and want to convert it to a single string in C#, you can use the string.Join() method to concatenate the strings in the collection. Here's an example:

using System.Linq; IQueryable<string> myStrings = GetMyStrings(); string result = string.Join(", ", myStrings); Console.WriteLine(result);

In this example, the GetMyStrings() method returns an IQueryable<string> that contains a collection of strings. The string.Join() method is used to concatenate the strings in the collection, separated by a comma and a space. The resulting string is stored in the result variable and printed to the console.

Note that the string.Join() method can also be used with other collections, such as IEnumerable<string> or List<string>. The method takes two parameters: the separator string and the collection of strings to concatenate. You can customize the separator string to match your requirements.
