Com of MS script control

Javascript has an eval method. Anyone who has used it knows its convenience and strength.

In C #, we can also use the COM component to execute JavaScript code.

The following code demonstrates how to use the msscriptcontrol component to execute a mathematical expression:

Msscriptcontrol. scriptcontrolclass SC = new msscriptcontrol. scriptcontrolclass ();
SC. Language = "JavaScript ";
Object OBJ = SC. eval ("1 + 2*(3 + 4 )");
Console. writeline (OBJ );

To use msscriptcontrol, you must reference the COM component Microsoft Script Control 1.0.

Another method is as follows:

// Csc.exe noname1.cs/R: C: \ WINDOWS \ Microsoft. NET \ framework \ v1.1.4322 \ Microsoft. jscript. dll

// Note: the Microsoft. JScript and Microsoft. VSA namespaces must be added.

Public class class1

{

Static void main (string [] ARGs)

{

System. Console. writeline ("Hello World ");

String expression = "Var result: Int = 0; Result = 1? \ "Success \": \ "Failure \"";

Microsoft. JScript. VSA. vsaengine VE = Microsoft. JScript. VSA. vsaengine. createengine ();

Console. writeline (Microsoft. JScript. Eval. jscriptevaluate (expression, VE ));

}

}
