Answer 1

Because of linq differed execution make use of tolist method and than get read data will do you task

var obj = empcls.SelectEmployeeById(3).ToList(); 
textvox.Text= obj[0].Nameofproperty;

Answer 2

.Where extension Method return IEnumerable List. so get The Top element or get Single Element from list.

EmployeeClass Emp  = empcls.SelectEmployeeById(3).ToList();  
if(listofEmp.Count() > 0)
{
EmployeeClass obj = listofEmp[0]; 
or 
EmployeeClass obj = listofEmp.Top(1);
or 
EmployeeClass obj = listofEmp.Single();

//then assign your values to testbox use class properties as:

txtSalEmpName.Text=obj.Name;
txtsalempcode.Text= obj.code;
}

You can do this as:

EmployeeClass Emp  = empcls.SelectEmployeeById(3).SingleOrDefault();
if(Emp != null)
{
txtSalEmpName.Text=obj.Name;
txtsalempcode.Text= obj.code;
}
