| - | ===== Source Code ===== | ||
| - | |||
| - | Here is a sample code of a component in C# (save this to a file called Your_CSharpBean_Name.cs) : | ||
| - | |||
| - | <code csharp> | ||
| - | using WComp.Beans; // Contains the definition of the [Bean] attribute | ||
| - | using System.Threading; // For the thread demo purposes | ||
| - | |||
| - | namespace Your_Namespace_Name { | ||
| - | |||
| - | [Bean] | ||
| - | public class Your_CSharpBean_Name { | ||
| - | |||
| - | public Your_CSharpBean_Name() { | ||
| - | // Put here your init instructions | ||
| - | // Example of a loop that call the output | ||
| - | // every second. | ||
| - | new Thread(new ThreadStart(ThreadLoopMethod)).Start(); | ||
| - | } | ||
| - | |||
| - | // Loop sample | ||
| - | public void ThreadLoopMethod() { | ||
| - | while(Thread.CurrentThread.IsAlive) { | ||
| - | Thread.Sleep(1000); | ||
| - | double result; | ||
| - | // Check if the output is connected | ||
| - | if(Output_Sample != null) | ||
| - | // call the connected methods sequentially | ||
| - | result = Output_Sample(123); | ||
| - | // and so on... | ||
| - | } | ||
| - | } | ||
| - | |||
| - | // --- Start: Input port sample --- | ||
| - | // an input port is a method (below) | ||
| - | public int Input_Sample(string param_name) { | ||
| - | string pn = param_name; // You may use the parameters | ||
| - | return 0; // You may return anything | ||
| - | } | ||
| - | // --- End: Input port sample --- | ||
| - | |||
| - | // --- Start: Output port sample --- | ||
| - | public delegate double Output_Sample_Signature(int param_name); | ||
| - | // This is the signature of the output method | ||
| - | public event Output_Sample_Signature Output_Sample; | ||
| - | // The output port is the event, named here Output_Sample | ||
| - | // --- End: Output port sample --- | ||
| - | } | ||

| - | ===== Compilation ===== | ||
| - | |||
| - | Here is a sample of the command line compilation: | ||
| - | <code> | ||
| - | csc.exe /target:library /r:Beans.dll Sample_Component.cs | ||
| - | </code> | ||
| - | |||
| - | You will find Beans.dll in the SharpWComp distrib. | ||
