这篇文章主要给大家介绍了.net中用icsharpcode.texteditor自定义代码折叠与高亮的相关资料,文中通过示例代码与图片介绍的很详细,需要的朋友可以参考借鉴,下面来一起看看吧。
前言
icsharpcode.texteditor 是一款非常不错的.net代码编辑控件,内置了多种高亮语言支持,同时完美支持中文,非常赞!
先来看一下运行效果:
一、项目结构
这里需要注意lib文件夹下导入的类库,这个demo需要这些dll.
二、代码折叠
需要实现ifoldingstrategy中的 generatefoldmarkers 方法,代码如下:
using icsharpcode.texteditor.document;
using system;
using system.collections.generic;
using system.linq;
using system.text;
using system.threading.tasks;
namespace jackwangcumt.winform
{
/// <summary>
/// the class to generate the foldings, it implements icsharpcode.texteditor.document.ifoldingstrategy
/// </summary>
public class mingfolding : ifoldingstrategy
{
/// <summary>
/// generates the foldings for our document.
/// </summary>
/// <param name="document">the current document.</param>
/// <param name="filename">the filename of the document.</param>
/// <param name="parseinformation">extra parse information, not used in this sample.</param>
/// <returns>a list of foldmarkers.</returns>
public list<foldmarker> generatefoldmarkers(idocument document, string filename, object parseinformation)
{
list<foldmarker> list = new list<foldmarker>();
//stack 先进先出
var startlines = new stack<int>();
// create foldmarkers for the whole document, enumerate through every line.
for (int i = 0; i < document.totalnumberoflines; i++)
{
// get the text of current line.
string text = document.gettext(document.getlinesegment(i));
if (text.trim().startswith("#region")) // look for method starts
{
startlines.push(i);
}
if (text.trim().startswith("#endregion")) // look for method endings
{
int start = startlines.pop();
// add a new foldmarker to the list.
// document = the current document
// start = the start line for the foldmarker
// document.getlinesegment(start).length = the ending of the current line = the start column of our foldmarker.
// i = the current line = end line of the foldmarker.
// 7 = the end column
list.add(new foldmarker(document, start, document.getlinesegment(start).length, i, 57, foldtype.region, "..."));
}
//支持嵌套 {}
if (text.trim().startswith("{")) // look for method starts
{
startlines.push(i);
}
if (text.trim().startswith("}")) // look for method endings
{
if (startlines.count > 0)
{
int start = startlines.pop();
list.add(new foldmarker(document, start, document.getlinesegment(start).length, i, 57, foldtype.typebody, "...}"));
}
}
// /// <summary>
if (text.trim().startswith("/// <summary>")) // look for method starts
{
startlines.push(i);
}
if (text.trim().startswith("/// <returns>")) // look for method endings
{
int start = startlines.pop();
//获取注释文本(包括空格)
string display = document.gettext(document.getlinesegment(start + 1).offset, document.getlinesegment(start + 1).length);
//remove ///
display = display.trim().trimstart('/');
list.add(new foldmarker(document, start, document.getlinesegment(start).length, i, 57, foldtype.typebody, display));
}
}
return list;
}
}
}
三、高亮配置
拷贝csharp-mode.xshd为 jackcsharp-mode.xshd ,将其中的名字修改为: syntaxdefinition name = "jackc#" ,并添加高亮关键字,如下:
这样代码中出现的jackwang就会高亮。下面的代码片段将自定义高亮文件进行加载,并用sethighlighting进行设置,这里一定注意目录下必须有xshd的配置文件,否则高亮将失效。
texteditor.encoding = system.text.encoding.utf8;
texteditor.font = new font("hack",12);
texteditor.document.foldingmanager.foldingstrategy = new jackwangcumt.winform.mingfolding();
texteditor.text = samplecode;
//自定义代码高亮
string path = application.startuppath+ "\\highlighting";
filesyntaxmodeprovider fsmp;
if (directory.exists(path))
{
fsmp = new filesyntaxmodeprovider(path);
highlightingmanager.manager.addsyntaxmodefileprovider(fsmp);
texteditor.sethighlighting("jackc#");
}
为了保持代码适时进行折叠,这里监听文本变化,如下所示:
private void texteditor_textchanged(object sender, eventargs e)
{
//更新,以便进行代码折叠
texteditor.document.foldingmanager.updatefoldings(null, null);
}
最后说明的是,我们可以定义一个格式化代码的类,来格式化c#代码:
