using (ClientContext ctx = new ClientContext(siteUrl))
{
if (siteUrl.ToLower().Contains(_SiteFormat)) ctx.Credentials = new SharePointOnlineCredentials

(userName, pwd);
else ctx.Credentials = new System.Net.NetworkCredential(userName, pwdS);

Web web = ctx.Web;
ListCollection listColl = web.Lists;

ListCreationInformation LCinfo = new ListCreationInformation();
LCinfo.Title = ListName;
LCinfo.TemplateType = (int)ListTemplateType.GenericList;
LCinfo.Description = "First Dynamic List";
listColl.Add(LCinfo);

ctx.Load(listColl);
ctx.ExecuteQuery();
List tList = listColl.GetByTitle(ListName);
FieldCollection fcol = tList.Fields;
FieldType colType = FieldType.Text;

//(error: Parameter overloaded for following line of code)

tList.Fields.Add("EmpId", colType, true);

tList.Update();
Console.WriteLine("Lists on the current site:\n\n");
}
}

Already tried 'newList.Fields.Add("My Column", FieldType.Text, true);'

Thank you... I was able to resolve it.

The working code is:

using (ClientContext ctx = new ClientContext(siteUrl))
{
if (siteUrl.ToLower().Contains(_SiteFormat)) ctx.Credentials = new SharePointOnlineCredentials(userName, pwd);
else ctx.Credentials = new System.Net.NetworkCredential(userName, pwdS);
Web web = ctx.Web;
ListCollection listColl = web.Lists;
//List Creation
ListCreationInformation LCinfo = new ListCreationInformation();
LCinfo.Title = ListName;
LCinfo.TemplateType = (int)ListTemplateType.GenericList;
LCinfo.Description = "First Dynamic List";
listColl.Add(LCinfo);
ctx.Load(listColl);
ctx.ExecuteQuery();
// Column creatton
List tList = web.Lists.GetByTitle(ListName);
Field tField = tList.Fields.AddFieldAsXml("", true, AddFieldOptions.DefaultValue);
Field dField = tList.Fields.AddFieldAsXml("", true, AddFieldOptions.DefaultValue);
tList.Update();
ctx.ExecuteQuery();
}
