Examples
Here is how to declare a CsParser and handle its events from the C# code:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
var parser = new Alternet.Syntax.Parsers.Roslyn.CsParser();
var edit = new Alternet.Editor.SyntaxEdit();
edit.Parent = this;
edit.Lexer = parser;
string fileName = "myfile.cs";
if (System.IO.File.Exists(fileName))
{
parser.FileName = fileName;
edit.LoadFile(fileName);
}
parser.TextReparsed += CsParser_TextReparsed;
}
private void CsParser_TextReparsed(object sender, EventArgs e)
{
var parser = sender as Alternet.Syntax.Parsers.Roslyn.CsParser;
parser.FindReferences(new System.Drawing.Point(0, 0));
}
}
Here is how to declare a CsParser and handle its events from the Visual Basic code:
Partial Public Class Form1
Inherits Form
Public Sub New()
InitializeComponent()
End Sub
Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
Dim parser = New Alternet.Syntax.Parsers.Roslyn.CsParser()
Dim edit = New Alternet.Editor.SyntaxEdit()
edit.Parent = Me
edit.Lexer = parser
Dim fileName As String = "myfile.cs"
If System.IO.File.Exists(fileName) Then
parser.FileName = fileName
edit.LoadFile(fileName)
End If
AddHandler parser.TextReparsed, AddressOf Me.CsParser_TextReparsed
End Sub
Private Sub CsParser_TextReparsed(ByVal sender As Object, ByVal e As EventArgs)
Dim parser = TryCast(sender, Alternet.Syntax.Parsers.Roslyn.CsParser)
parser.FindReferences(New System.Drawing.Point(0, 0))
End Sub
End Class
Remarks
CsParser is a non-visual component designed to perform syntax highlighting and provide advanced code editing capabilities for the C# language. This parser uses the Microsoft Code Analysis (Roslyn) API and performs full syntax and semantic analysis of the C# code, supporting up to C#10 language specification. When linked to the SyntaxEdit or TextEditor controls, this parser drives additional features such as code completion, code outlining, code formatting, highlighting types in different colors, and underlying syntax and semantic errors and warnings.
Here are some of the essential features provided by the CsParser:
- Syntax Highlighting
- IntelliSense (Code completion)
- Signature Help (displaying parameter information for methods)
- Code Outlining
- Structure guidelines
- Formatting a selected block of text or the whole document.
- Finding declarations and references
Constructors
- CsParser()
Initializes a new instance of the
CsParser
class with default settings.
- CsParser(IRoslynSolution)
Initializes a new instance of the
CsParser
class with specifiedIRoslynSolution
.
