Hello Ramco, Try below: BALStudents bALStudents = new BALStudents(); List objStudentList = bALStudents.GetAvailableStudntList(Convert.ToInt32(colum.GroupID)); if (objStudentList != null) { string commaSeparatedValues = string.Join(",", objStudentList.Select(s => s.StudentName)); // The above line will concatenate all the StudentName values with comma separation. // You can replace "StudentName" with any property you want to include in the string. // If you want to exclude the last comma, you can use the following code instead: // string commaSeparatedValues = string.Join(",", objStudentList.Select(s => s.StudentName)).TrimEnd(','); } Thanks Naimish Makwana

Hello Ramco, Please try this one, BALStudents bALStudents = new BALStudents(); List objStudentList = bALStudents.GetAvailableStudntList(Convert.ToInt32(colum.GroupID)); string commaseperatedStudentName = ""; if (objStudentList != null) { commaseperatedStudentName = string.Join(",", objStudentList.Select(c => string.Format("{0} - {1}", c.Name, c.MobileNo)).ToList()); }

Hello Ramco, As Naimish told you can create comma seperated list using string.Join(",",ListOfValue), string.Join(",",ListOfValue) takes two parameter 1. First Parameter Which is seperator you want to use in your case , (comma) 2. Second Parameter Which is list Object your want to club togather Below code will gives you commaSeperated studentIds, Its depend on your requirement you can change field name. BALStudents bALStudents = new BALStudents(); List objStudentList = bALStudents.GetAvailableStudntList(Convert.ToInt32(colum.GroupID)); if (objStudentList != null) { string commaSeparatedValues = string.Join(",", objStudentList.Select(s => s.StudentId).ToList()); }

Hi i have written below code but comma's not getting inserted between 2 names Chilumuri - 9814604990Rana - 7738499995 foreach (var colum1 in objStudentList) { StudentDetail objResult = bALStudents.GetStudentDetailByLoginID(Convert.ToInt32(colum1.StudentID)); StudentName += string.Join(",", objResult.Name+objResult.MobileNo)+ "" ; }

foreach (StudentDetail student in objStudentList) { string name = student.Name; // Do something with the name variable } In the given code, the objStudentList variable is a List of StudentDetail objects which are obtained by calling the GetAvailableStudntList method of BALStudents object with a parameter of colum.GroupID . To extract values from the objStudentList object, you can use a loop like a for loop or foreach loop. Here's an example using foreach loop to iterate over the objStudentList and extract the Name property of each StudentDetail object: n this example, the Name property of each StudentDetail object is extracted and stored in the name variable. You can then use this variable for further processing.
