Assigning listItems to single string by comma separated

Question

I have a listItems which I want to assign to a string. SO I tried like below

for (int i = 0; i < LocationDetails.Count; i++)
{
    strMaintZone = String.Join(",", LocationDetails[i].LocationID);
}

But it is not getting assigned and it takes the last value. How do I assign the value to the string.

LINQ can be helpful here. You should pass IEnumerable<string> to string.Join method. The IEnumerable<string> can be made by LINQ Select clause.

strMaintZone = string.Join(",", LocationDetails.Select(item => item.LocationID));

In your example problem is that you every time override the value of strMaintZone, and as a result you will have only the last element.
