Extract values in a string

Hi Jignesh

 I have written like below . How i should remove last comma

StudentName += objResult.Name + "" + "," + " ";

Thanks

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,

 BALStudents bALStudents = new BALStudents();
            List objStudentList = bALStudents.GetAvailableStudntList(Convert.ToInt32(colum.GroupID));
            if (objStudentList != null)
            {
                string studentNameCommaseperated = string.Join(",", objStudentList.Select(c => new {StudentName = string.Format("{0} - {1}", c.Name, c.MobileNo) }).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.

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());
}

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
