.Net User EFI interface

Updated.

Now 3 test projects available: c#, vb.net and c++/cli. All based on .net 2.0.

Updated.

- echo functions added;

- small changes.

Simple examples are attached (pdf files).

Updated.

- error handling added (only one function in the assembly may contain a static field Errors - array of strings).

For example:

using System;

public partial class cserror {

public static String[] Errors = {

"cserror 1",

"cserror 2",

"cserror 3",

"cserror 4"

};

}

How to use:

using System;

using NetEFI;

public partial class cserror: IFunction {

public FunctionInfo Info {

get {

return new FunctionInfo( "cserror", "n", "return error string",

typeof( String ), new[] { typeof( TComplex ) } );

}

}

public FunctionInfo GetFunctionInfo( string lang ) { return Info; }

public bool NumericEvaluation( object[] args, out object result ) {

throw new EFIException( ( int ) ( ( TComplex ) args[0] ).Real, 1 );

}

}

EFIException( ErrNum, ArgNum) - like in MAKELRESULT().

Updated (github).

Now you can use context:

public bool NumericEvaluation( object[] args, out object result, ref Context context ) {

//while ( !context.IsUserInterrupted ) { }

if ( context.IsDefined( "vbecho" ) ) {

context[ "vbecho" ].NumericEvaluation( args, out result, ref context );

} else {

result = Evaluate( ( string ) args[0] );

}

return true;

}

public string Evaluate( string text ) {

return text;

}

How it works (rus): Внедрение кода с пользой

Tested for MC15 M050 x32 and MC Prime 6.0 x64. Now you can use .net (c#, vb.net, c++/cli) user functions in x64 Mathcad Prime.

- 64-bit support added.

[21-01-2021]
- TComplex changed to .Net Complex from System.Numerics;
- refactored.

[19-01-2021]
- added support utf-8 for result string;
- added example project "capture".

[18-01-2021]
- only for 32-bit systems;
- mc15 m050 tested;
- .net 4.0 supported;
- examples for vs2019.

Now we can increase the speed of calculations. In this example in 5 times. Part of the function is implemented in the plugin.
