创建xml对应的对象类
根节点，对应类名
[XmlRoot("ComponentLog")]
publicclassComponentLog{
}
其他节点，对应属性名
[XmlElement("LogCategory")]
publicstringlogCategory{get;set;}
也可以对应集合(如果同一节点有多个的话)
[XmlElement("LogContent")]
publicList<LogContent>logContent{get;set;}
节点里的内容
[XmlAttribute("Content")]
publicstringcontent{get;set;}
XML文件：
<?xmlversion="1.0"encoding="utf-8"?>
<ComponentLog>
<LogCategory>Sign</LogCategory>
<LogContent>
<Key>1</Key>
<ContentCaptionContent="内容1"VariableName=""/>
<ContentDetailContent="内容2"VariableName=""/>
</LogContent>
<LogContent>
<Key>2</Key>
<ContentCaptionContent="内容3"VariableName=""/>
<ContentDetailContent="内容4"VariableName=""/>
</LogContent>
</ComponentLog>
窗体中打开文件夹
FolderBrowserDialogfolderBrowser=newFolderBrowserDialog();
if(folderBrowser.ShowDialog()==DialogResult.OK)
{
txtFolderPath.Text=folderBrowser.SelectedPath;
}
窗体中跨线程调用组件(控件)
///<paramname="textBox">文本框</param>
///<paramname="strText">要显示的内容</param>
privatevoidShowText(TextBoxtextBox,StringstrText)
{
if(this.InvokeRequired)
{
this.Invoke((MethodInvoker)delegate(){ShowText(textBox,strText+"\r\n");});
}
else
{
textBox.Text+=DateTime.Now+""+strText+"\r\n";
}
}
关闭窗口，退出所有进程
privatevoidForm1_FormClosed(objectsender,FormClosedEventArgse)
{
System.Environment.Exit(0);
}
将文本框的滚动条一直处于最低端
privatevoidtxtReceive_TextChanged(objectsender,EventArgse)
{
txtReceive.SelectionStart=txtReceive.Text.Length;
txtReceive.ScrollToCaret();
}
连接字符串
//str1不为空，就将str1和“”连接
stringjournalString=str1!=string.Empty?string.Concat(str1,""):string.Empty;
获得程序运行目录下指定文件的路径
stringxmlPath=Path.Combine(AppDomain.CurrentDomain.BaseDirectory,"JournalLog\\123.xml");
获取指定的编码格式
Encodinggb2312=Encoding.GetEncoding("GB2312");
按照指定编码格式读取文本内容
stringstrRead=File.ReadAllText(xmlPath,Encoding.Default);
按照指定编码格式转换已经读取到的文本内容
//sendByte是字节，将其转换成string
stringstrSendData=gb2312.GetString(sendByte);
或者stringstrSendData=Encoding.UTF8.GetString(sendByte);
