i did something like below:

C#

string name="something";

var upload = new Upload
            {
                UploadID=1,
                ImageName = name,

            };

here Upload is a class name which has two property like:

C#

public class Upload
    {
        public int UploadID { get; set; }
        public string ImageName { get; set; }
    }

it's not possible to assign a string to a class type . So how can I convert the string type to the upload class type???

If i understand you well...
It's possible, but you need to define class constructor[^].

C#

public class Upload
    {
        //variables
        private int id=0;
        private string simagename = String.Empty;

        //
        public Upload(int iid, string sname){id = iid; simagename = sname;}
        public int UploadID { get; set; }
        public string ImageName { get; set; }
    }

Usage:

C#

Upload u = new Upload(1, "something");

or

C#

int myid = 1;
string simagename = "Wallpaper.jpg";
Upload u = new Upload(myid, simagename);

but what's the relationship with simagename and ImageName, as I need ImageName.

That should work fine - if you are targeting V3.0 or above of the .NET framework - it won't work below that.
MSDN: Object Initializers[^]
For example, this works:

C#

class Program
    {
    static void Main(string[] args)
        {
        string name = "something";

        var upload = new Upload
        {
            UploadID = 1,
            ImageName = name,
        };
        Console.ReadLine();
        }
    }
public class Upload
    {
    public int UploadID { get; set; }
    public string ImageName { get; set; }
    }
