I had a 14 digit create datetime and resolved datetime in float time format and I could parse the date using following conversion:
CONVERT(datetime, LEFT(CAST(CAST(is_resolved_datetime as BigInt) as varchar(14)),8)+' '+
SUBSTRING(CAST(CAST(is_resolved_datetime as BigInt) as varchar(14)),9,2)+':'+
SUBSTRING(CAST(CAST(is_resolved_datetime as BigInt) as varchar(14)),11,2)+':'+
SUBSTRING(CAST(CAST(is_resolved_datetime as BigInt) as varchar(14)),13,2))
If I were to extract only the time difference of two datetimes in hr:min:sec.

I am using a viewstate to store the company Ids and splitting at hyphen.
protected void onCompanychange(object sender, EventArgs e) {
ViewState["companyID"] += companydropdown.SelectedValue + "-";
String companyids = ViewState["companyID"].ToString();
string pattern = "-";
company_array = Regex.Split(companyids, pattern);
company_length = company_array.Length;
}
Company array is a string array where i have stored the company ids
the problem is company_array[0] has the initial value of the dropdownlist(company) --select company which is why m getting the error(cannot convert data type nvarchar to int) . I have used the same logic in many places in my project it did not give any error.
int count = 0;
company_length = company_length - 1;
while (count < GridView3.Rows.Count && compid_counter < company_length ) {
cmd = new SqlCommand("insertWorkDetais", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@trainerId",trainerID);
