How do you program a database (console programming) c#?

Question

I'm sorry about this. I'm a newbie to programming, and I was set to do a database of some sorts in c#. This application has to run on the CMD or 'console' as the progam calls it. Anyway, I was trying and came up with this.

class Program
{
static void Main(string[] args)
{
string sName;
Console.WriteLine("Write your name:");

sName = Console.ReadLine("Name:" + sName);

Console.Read();
}
}

It doesn't work however. Theoretically, you should be able to type in your name and other data and the program would later show it all, together. My main problem is that I keep getting the error message "Cannot implicitly convert string to void" or "No overload method for ReadLine takes '1' arguments." Can you help me?

Answer 1

The specific fix for the problem you are seeing is to change your readline to this:



Console.ReadLine(sName);



Drop the prompt. You can include the prompt in a writeline statement.



Trying to do a database-style thing is a little tricky and you'll want to get basic file I/O and arrays under your belt first. But it can be done.



Good luck and keep coding.

The Console.ReadLine method only reads what you type in the console. Try the program like you have it, but just put Console.ReadLine() as I wrote it and get rid of Console.Read. If you want to display the name you just read, you could add a line like Console.WriteLine("Hello, {0}", sName); beneath the ReadLine call. I hope this helps and have fun with C# (it's a fun language).

Console.ReadLine() doesn't take any arguments. To accomplish what you want you have to do is something like:

Console.Write("Write your name: ");

string name = Console.ReadLine();



ReadLine is an input function, Write and WriteLine is an output function, you can't output in a readline statement. As for the database part you might want to look at the ADO.Net and the System.Data namespace, it contains the classes you need to accomplish an in-code database. Useful classes are:

DataTable <- represents a table of data.

DataRow <- represents a row of data in a datatable.

DataColumn <- represents a column in a datatable.

no longer anymore, at one time C++ became into in basic terms an extension of C. on account that then, C has replaced, and so has C++. although that being suggested that is commonplace for a similar application to hold at the same time the two C and C++. the tactic is a similar, yet there are basically some modifications int he libraries which you prefer the compiler to link to.
