C# 代码自动高亮着色（二）

Samples(这个主要是例子的图片了)

Demo application has many samples. Below is a brief description:

• Powerful sample. Contains many features: syntax highlighting, code folding, export, same words highlighting and other.
• PowerfulCSharpEditor. Powerful multitab C# source files editor. Supports highlighting, multitab backward/forward navigation, dynamic methods list, autocomplete and other.

做的很好了，功能也很多c#编程的!

• Simplest syntax highlighting sample. Shows how to make simplest syntax highlighting.
• Marker sample. Shows how to make marker tool. Sample uses class ShortcutStyle for create clickable markers on text area:

Custom style sample. This example shows how to create own custom style. Next custom style draws frame around of the words:

用户自定义的样式

class EllipseStyle : Style
{
    public override void Draw(Graphics gr, Point position, Range range)
    {
        //get size of rectangle
        Size size = GetSizeOfRange(range);
        //create rectangle
        Rectangle rect = new Rectangle(position, size);
        //inflate it
        rect.Inflate(2, 2);
        //get rounded rectangle
        var path = GetRoundedRectangle(rect, 7);
        //draw rounded rectangle
        gr.DrawPath(Pens.Red, path);
    }
}

• VisibleRangeChangedDelayed usage sample. This example shows how to highlight syntax for extremely large text by VisibleRangeChangedDelayed event.
• Simplest code folding sample. This example shows how to make simplest code folding.
• Custom code folding sample. This example shows how to make costom code folding (on example of Python).
• Autocomplete sample, Autocomplete sample 2. Examples show how to create autocomplete functionality:

• Tooltip sample. It shows tooltips for words under mouse.
• Dynamic highlighting sample. Shows how to make dynamic syntax highlighting. This example finds the functions declared in the program and dynamically highlights all of their entry into the code of LISP.
• Syntax highlighting by XML Description. This example uses XML file for description syntax highlighting.

例子居然是道德经的，喔喔!

Image drawing sample. Sample shows how to draw images instead of text:

 

• This example supports animated GIF too.

• AutoIndent sample. Sample shows how to make custom autoindent functionality.
• BookmarksSample. Sample shows how to make bookmarks functionality.
• Logger sample. It shows how to add text with predefined style:

Split sample. It shows how to make split-screen mode:

• Lazy loading sample. It shows how to work with files of extremally large size.
• Console sample. It shows how to create console emulator.
• HintSample. It shows how to use hints:

• ReadOnlySample. The example shows how to create readonly blocks of the text.
• MacrosSample. This sample shows how to use macros for hard formatting of the code.
• PredefinedStylesSample. Here we create large readonly text with predefined styles, hyperlinks and tooltips.
• Joke sample. It contains some additional features, implemented custom TextStyle:

Performance

For storing one megabyte of text requires approximately 6 MB of RAM (include undo/redo stack objects). The coloring does not consume significant resources.

The use of regular expressions and saving memory usage, allow to reach high performance component. I tested the file of 50,000 lines (about 1.6 MB) of C# code. The total time of insertion, and the syntax coloring was about 3 seconds. Further work with the text passed without significant delays.

Restrictions

The component does not support center or right alignment and uses only monospaced fonts. Also tabs are always replaced by spaces.
