Question

Dear Friends,

 

Kindly assist on the below

I am making program in Visual Studio 2008 C# for Windows CE 6 device (datalogic memor).

Trying to read data from a CSV file using below code

 

using System;

using System.Linq;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.IO;

using System.Windows.Forms;

 

 

private void cmdDataRefresh_Click(object sender, EventArgs e)

{

if (!File.Exists(@"d:\\SampleSale.csv"))

{

Console.WriteLine("{0} not exist.");

}

StreamReader reader = new StreamReader(File.OpenRead(@"SampleSale.csv"));

}

 

 

But i get an error while running the code at the line StreamReader 

 

 

 

 

Can you help on this? how to specify the file with path and why this error comes up?

 

Thanks

 

 

 

 

Answer 1

Well, C# is much easier to learn and use than C++ which is the language which has been traditionally used for games development.

However, it's still a strongly typed language and is not therefore as easy to use as a dynamic language such as Python. However, it does produce much faster executables (though not as fast as C++) which is, of course, an important consideration for games.

With regard to whether to use C# (and XNA) or C++, you may find this article interesting (http://www.fairyengine.com/articles/cppvscsharp.htm).

Rather than try to learn a language like C# from a website, I'd buy yourself a book which will give you a more orderly knowledge. The time it will take you to become proficient will depend, amongst other things, on what experience you have with other programming languages.

Answer 2

I am not familiar with Python but I suspect it is easier because it is usually used for things that are easier to do or things that it is designed to make easy. Like I said, I do not know Python, but it might be more difficult to use for doing other things that is done easier in C#.

I personally consider C++ to be a little easier, especially when it comes to some things in C# that is not clearly defined. For example, C# garbage collection can make things really easy and really confusing. Reference types confuse people, such as when they are compared for equality and then that does not give the results the developer expects.

C# is complex and powserful. There is a lot to learn and many ways to use it. The design of languages such as C++, C# and Java are the result of many years of experience by many experts. It will take time to get the benefit of that experience but there are many vast resources to explore.

Answer 3

Thanx for your answers.

Creating a simple "hangman " program was not difficult as it uses almost no pre-defined classes.

But how much time (how many hours) to learn is needed to create a Win GUI application, or a database program or a web page or to use XNA for simple 2d game?

Is there a desired path of learning the language?

I have good Python/PyGame and good Pascal knowledge, (and good RPG :))

Thanx if you can further clear the fog in front of me...

Answer 4

You can learn C# by going to home page of C# Corner and click on Beginners link on the header.

Answer 5

I agree! C# is much easier to learn and use than any other object oriented languages out there.
