Sending data to crystal report by text box from C#

Question

Hi Dears:

I am going to make a program that takes some text controls in a C# project and then when we submit the form the values of text boxes goes to a pre-made report and substitute there, then the user can print it.

for example in VS I have a text box that takes the Name, and I want in the crystal report to show this : I am [txtName]. that [txtName] have to be substitute by the value of text box txtName in VS and will be shown in Crystal Report.

and finally it will be :

I am Soroosh.


What should I do?

I do not need any Data Base. It's a DB Free Program.

Please if you know the answer tell me in details not in summary I am a newbie in C#.

Thanks in advance.
