public class ScriptRun : Component, IComponent, IDisposable, IScriptRun, IScriptRunBase, ITypeDefinitionsLocator

Remarks

ScriptRun is a non-visual component that allows executing JavaScript or TypeScript scripts and script projects; it allows referencing third-party assemblies and registering application-defined objects to be accessible in the scripts.

The most important properties and methods of the ScriptRun are:

The ScriptHost property provides properties and methods of the underlying scripting engine and allows adding application-specific objects to the script.

The ScriptSource property contains the source of the script to execute.

The Run() method executes the script.

The RunFunction method executes the specified script function.

Examples

Here is how to run TypeScript script using ScriptRun from the C# code:

public partial class Form1 : Form
{
    private void Form1_Load(object sender, EventArgs e)
    {
        var scriptRun = new Alternet.Scripter.TypeScript.ScriptRun();
        scriptRun.ScriptSource.FromScriptFile(@"c:\myscript.ts");
        scriptRun.Run();
    }
}

Here is how to run TypeScript script using ScriptRun from the Visual Basic code:

Partial Public Class Form1
    Inherits Form

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
        Dim scriptRun = New Alternet.Scripter.TypeScript.ScriptRun()
        scriptRun.ScriptSource.FromScriptFile("c:\myscript.ts")
        scriptRun.Run()
    End Sub
End Class

ProjectDirectory	Gets or sets root project directory.
ScriptHost	Returns object that implements `IScriptHost` interface for this runner.
ScriptLanguage	Gets or sets programming language of the script.
ScriptSource	Gets source of the script to execute.
TypeDefinitionsSearchPaths	Gets or sets list of search directories to look for type definitions.
WaitForDebuggerOnStart	Gets of sets a boolean value indicates whether script engine is to wait for a debugger connection and schedule a pause before executing the first line of application script code.
