Entity Framework error whilepopulate the TextBox in the form

Question

I got the error while populating dropdownlist in Entity Framework.

 

private void PopulateFormFieds(int userID)
{
    UserManager userMgr = new UserManager();
    var result = userMgr.GetUserDetail(userID);
    if (result.Count > 0)
    {
        var user = result.First();
        tbFirstName.Text = user.FirstName;
        tbLastName.Text = user.LastName;
        tbContactNumber.Text = user.ContactNumber;
    }
    else
    {
        //NO RECORDS FOUND.
        tbFirstName.Text = string.Empty;
        tbLastName.Text = string.Empty;
        tbContactNumber.Text = string.Empty;
    }
}

protected void ddlUser_SelectedIndexChanged(object sender, EventArgs e)
{
    PopulateFormFieds(Convert.ToInt32(ddlUser.SelectedItem.Value));
}

Operator '>' cannot be applied to operands of type 'method group' and 'int'  in 

 

 if (result.Count > 0)  

 

 Help me to resolve the problem.Thank You.
