left hand side of an assignment must be a variable

Trying to put an integer data from database(Linq to sql) into a label getting this error exception:

left-hand side of an assignment must be a variable property or
indexer

Code:

protected void Page_Load(object sender, EventArgs e)
{
   DataClassesDataContext data = new DataClassesDataContext();

   var visit = (from v in data.SeeSites where v.Date == todaydate select v).FirstOrDefault();
   int seennow = visit.See; // On This line I can put data in seenow variable, no problem

   Convert.ToInt64(lblSeeNow.Text) = visit.See;   // exception error appears here
}

Method 1

Try:

if (visit.See != null) {
    lblSeeNow.Text = visit.See.ToString();
}

You cannot assign something to a function result. In your case lblSeeNow.Text is of type String hence usage of ToString(); method of your Int value.

Method 2

You need to use

 lblSeeNow.Text = visit.See.ToString();

Method 3

Convert.ToInt64(lblSeeNow.Text) = visit.See;

As you mentioned, this is the issue.

Convert.ToInt64 is a method. But you’re trying to save a value to it.

You can’t.

Just do this

lblSeeNow.Text = visit.See.ToString();

Method 4

I think you want

lblSeeNow.Text = visit.See.ToString();

You can’t assign anything to

Convert.ToInt64(lblSeeNow.Text)

because it evaluates to a number.

Method 5

Convert.ToInt64(lblSeeNow.Text) isn’t a variable. It takes the value in lblSeeNow.Text and converts it to a long. There isn’t a variable to store stuff in anymore.

You probably want this:

lblSeeeNow.Text = visit.See.ToString();

Method 6

You should convert the integer to string, also add a check for being sure that visit is not null

lblSeeNow.Text = visit != null ? visit.See.ToString() : string.Empty
