using System; using System.Collections.Generic; public async List ConvertObjToArray(object obj) { if (obj is IEnumerable stringArray) { List convertedArray = new List (stringArray); int count = convertedArray.Count; return convertedArray; } else { // Handle the case where the object is not an array of strings. // You can throw an exception or return an empty list, depending on your use case. return new List (); } }

To achieve this, first determine the type of the object and then convert it accordingly. Since the method signature you provided is for a list of strings, Here's how you can do it: public async Task ConvertObjToArray(object obj) { if (obj is null) { return new string[0]; // Return an empty array if the object is null } if (obj is string str) // Check if the object is already a string { return new string[] { str }; // Convert the string to a string array with one element } if (obj is IEnumerable stringList) // Check if the object is a collection of strings { return stringList.ToArray(); // Convert the collection to a string array } }

Please use the code below which will calculate the count aswell as it will convert obj into array public async Task > ConvertObjToArray(object obj) { if (obj is IEnumerable stringArray) { List result = stringArray.ToList(); int count = result.Count; return result; } else { // Handle the case where the object cannot be converted to an array of strings. // You might throw an exception or return an empty list based on your requirements. return new List (); } }
