try
{

FileUpload1.PostedFile.SaveAs(filename);

string[] Lines = File.ReadAllLines(filename);
string[] Fields;

Lines = Lines.Skip(1).ToArray();
List<employeemaster> emlist = new List<employeemaster>();

foreach (var line in Lines)
{
Fields = line.Split(new char[] { ',' });
emlist.Add(
new EmployeeMaster
{
EmployeeID = Fields[0].Replace("\"", ""),
CompanyName = Fields[1].Replace("\"", ""),
ContactName = Fields[2].Replace("\"", ""),
ContactTitle = Fields[3].Replace("\"", ""),
CompanyAddress = Fields[4].Replace("\"", ""),
PostalCode_ = Fields[5].Replace("\"", ""),

});
}

using (MuDatabaseEntities dc = new MuDatabaseEntities())
{
foreach (var i in emlist)
{
var v = dc.EmployeeMasters.Where(a => a.EmployeeID.Equals(i.EmployeeID)).FirstOrDefault();
if (v != null)
{
v.EmployeeID = i.EmployeeID;
v.CompanyName = i.CompanyName;
v.ContactName = i.ContactName;
v.ContactTitle = i.ContactTitle;
v.CompanyAddress = i.CompanyAddress;
v.PostalCode_ = i.PostalCode_;
}
else
{
dc.EmployeeMasters.Add(i);
}
}

dc.SaveChanges();
this is also another example with 6 fields but when in csv file
i get
company address-"54,abc,HBC"
then 54 abc HBC treated as different field.
i need it within " " field must be treated as single one in ASP

C#

static void EmbeddedCommas()
        {
            string input =@"1997,Ford,E350,""Super, luxurious truck""";
            string[] inputArray;
            inputArray = input.Split(',');
            int count = 0;
            int maxCount = 4;
            string[] outputArray = new string[maxCount];

            foreach (var item in inputArray)
            {
                if (count < maxCount - 1)
                {
                    outputArray[count] = item;
                    input = input.Remove(0, outputArray[count].Length + 1);
                    count++;
                }
                else
                {
                    outputArray[count] = input.Replace('"',' ');
                }

            }

            foreach (var item in outputArray)
            {
                Console.WriteLine(item);
            }
            Console.ReadLine();
        }

csv: Comma Separated Values
Look for a library which can read csv files!
