Step 1: Open Visual Studio.
Step 2: Select File -> New -> Project
Step 3: Select Visual C# Template
Step 4: Select Console Application
Step 5: Give Name of Application and Click on OK Button.
Visual Studio will open a Program.cs File; File will have some Namespaces, Class and Main Method.
Step 6: Write the following code (Print number from 1 to 100) in Main Method.
{
for(int count=1;count<=10;count++)
{
Console.WriteLine(count);
}
Console.Read();

You've been here 4 1/2 years and you think that is a question?

That looks like your homework instructions: I'd strongly suggest you read them carefully and do exactly what they say.
Then, press F5 which will compile and (if you typed it all correctly) run your program.
It won't however do what it says it will: there is a bug in the code or the description of the code.

I would remove the letter 'i' declared above the for() loop, and use the var keyword inside the for instead. Other than this observation, I am not sure what your question is.

You can try asking the author if he's interested in making a video version: there is a forum at the bottom of the article which lets you communicate with him.
But ... that article was written in 2004, so his interests have probably moved on since then. And he hasn't logged in for over three years, so he isn't necessarily interested in the site anymore.
If I was you, I'd read the article: a video tutorial is going to cover the same ground, but in less detail, and probably in a much worse format.

Who exactly do you want to make this video tutorial, and what do you think you'll get out of it that you can't get from the tutorial?
This space for rent

Copy and paste is to easy.. but understanding code is difficult... how its work and why its work
|
|
|
|

And you won't get that from most video tutorials - they are generally made by people who can't read and write, much less explain how things work!
I've yet to see a code-based video tutorial that was better than the text-based equivalent.

That would be an interesting C# video tutorial to create. I will keep this in mind on my Youtube C# video channel.

How to call the load runner (LR) controller from visual studio
|
|
|
|
|
|
Install the Visual Studio add-in on the LoadRunner CD: open its UI, read the 'ReadMe file.
«Differences between Big-Endians, who broke eggs at the larger end, and Little-Endians gave rise to six rebellions: one Emperor lost his life, another his crown. The Lilliputian religion says an egg should be broken on the convenient end, which is now interpreted by the Lilliputians as the smaller end. Big-Endians gained favor in Blefuscu.» J.

In the diagram given in below link for each customer I want to select all orders and then for each order I have calculate a TotalPrice = (Sum of all Food Items included in order * Quantity) + ExtraPrice. I am struggling to create a query for it using linq to sql.I need to select OrderId, Date and TotalPrice and it should include a where clause for comparing customer ID.
<a href="https://prnt.sc/fwf7ca">Relationship Diagram</a>
What I have tried:
dc.orders.Select(o => new { o.orderId, o.date, TotalPrice = ( (o.orderLines.Select(ol => ol.foodItem.price).Sum() * decimal.Parse(o.orderLines.Select(ox => ox.quantity).ToString())) + decimal.Parse(o.orderLines.Select(x => x.extraPrice).ToString())) } );

Also posted in QA: OP advised to remove one of the two. Possibly homework ?

Stop and think about what you're trying to do.

You're taking a query and converting it to a string. That will most likely return the SQL query - "SELECT quantity FROM ...". You then try to parse that SQL query as a decimal, which will throw an exception.
And even if it worked, you can't calculate the total like that anyway. For example, (1 × 10) + (2 × 5) is not that same as (1 + 2) × (10 + 5)!
For each line, you want to multiply the price by the quantity, then add the extra price. You then want to sum the results up to get the total price:
o.orderLines.Sum(ol => (ol.foodItem.price * ol.quantity) + ol.extraPrice)
If you want to filter the orders, then add a Where call[^] before the Select call.
dc.orders.Where(o => ...).Select(o => ...);

var res = (from a in dc.orders
join b in dc.orderLines on a.orderId equals b.fk_orderId
join c in dc.foodItems on b.fk_foodId equals c.foodId
where a.fk_custId == cID
group new { a,c,b } by a into g
select new
{
OID1 = g.Key.orderId,
date1 = g.Key.date,
val = g.Sum(x => x.c.price * x.b.quantity) + g.Select(d => d.b.quantity)
});
I have created the above query. Now the only problem is in the last line (val = g.Sum(x => x.c.price * x.b.quantity) + g.Select(d => d.b.quantity)).
It shows error (Operator + cannot be applied to operand of type decimal? and System.Collection.Generic.IENumerable<int?>
Can you please help.
