創建xml對應的對象類

根節點，對應類名

[XmlRoot("ComponentLog ")]

public class ComponentLog{

}

其他節點，對應屬性名

[XmlElement("LogCategory")]

public string logCategory { get; set; }

也可以對應集合(如果同一節點有多個的話)

[XmlElement("LogContent")]

public List<LogContent> logContent { get; set; }

節點里的內容

[XmlAttribute("Content")]

public string content { get; set; }

?

XML文件：

<?xml version="1.0" encoding="utf-8"?>

<ComponentLog>

???????? <LogCategory>Sign</LogCategory>

???????? <LogContent>

??????? <Key>1</Key>

??????? <ContentCaption Content="內容1" VariableName=""/>

??????? <ContentDetail Content="內容2" VariableName="" />

??? </LogContent>

???????? <LogContent>

??????? <Key>2</Key>

??????? <ContentCaption Content="內容3" VariableName=""/>

??????? <ContentDetail Content="內容4" VariableName="" />

</LogContent>

</ComponentLog>

窗體中打開文件夾

FolderBrowserDialog? folderBrowser = new? FolderBrowserDialog();

??? if (folderBrowser.ShowDialog() == DialogResult.OK)

??? {

????? txtFolderPath.Text = folderBrowser.SelectedPath;

???? }

窗體中跨線程調用組件(控件)

??????? /// <param name="textBox">文本框</param>

??????? /// <param name="strText">要顯示的內容</param>

??????? private void ShowText(TextBox textBox, String strText)

??????? {

??????????? if (this.InvokeRequired)

??????????? {

????????????? ??this.Invoke((MethodInvoker)delegate () { ShowText(textBox, strText+"\r\n"); });

??????????? }

??????????? else

??????????? {

??????????????? textBox.Text += DateTime.Now + "?? " + strText+"\r\n";

??????????? }

??????? }

關閉窗口，退出所有進程

??????? private void Form1_FormClosed(object sender, FormClosedEventArgs e)

??????? {

??????????? System.Environment.Exit(0);

??????? }

將文本框的滾動條一直處于最低端

??????? private void txtReceive_TextChanged(object sender, EventArgs e)

??????? {

??????????? txtReceive.SelectionStart = txtReceive.Text.Length;

??????????? txtReceive.ScrollToCaret();

??????? }

連接字符串

//str1不為空，就將str1和“ ”連接

string journalString = str1 != string.Empty ? string.Concat(str1, " ") : string.Empty;

獲得程序運行目錄下指定文件的路徑

string xmlPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "JournalLog\\123.xml");

獲取指定的編碼格式

Encoding gb2312 = Encoding.GetEncoding("GB2312");

按照指定編碼格式讀取文本內容

string strRead = File.ReadAllText(xmlPath,Encoding.Default);

按照指定編碼格式轉換已經讀取到的文本內容

//sendByte是字節，將其轉換成string

string? strSendData = gb2312.GetString(sendByte);?

或者string? strSendData = Encoding.UTF8.GetString(sendByte);
