ICSharpCode.TextEditor 实现查找功能
int startindex = 0;
private void toolFind_Click(object sender, EventArgs e)
{
//设置选择的文本。
var text = this.txtFindText.Text;//取得要查找的文本
var offset = this.CodeEditor.Text.IndexOf(text, startindex,StringComparison.CurrentCultureIgnoreCase);
if (offset >= 0)
{
startindex = offset + text.Length;//为查找下一个做准备
var start = this.CodeEditor.Document.OffsetToPosition(offset);
var end = this.CodeEditor.Document.OffsetToPosition(offset + text.Length);
this.CodeEditor.ActiveTextAreaControl.SelectionManager.SetSelection(new DefaultSelection(this.CodeEditor.Document, start, end));
//滚动到选择的位置。
this.CodeEditor.ActiveTextAreaControl.Caret.Position = end;
this.CodeEditor.ActiveTextAreaControl.TextArea.ScrollToCaret();
} else {
startindex = 0;//循环查找
}
}
