C# WinForm 小技巧

1.窗体页面按键判断
（1）单键判断
if (e.KeyCode == Keys.Delete)
{
//处理逻辑
}
（2）组合建判断：
if (e.Modifiers.CompareTo(Keys.Control) == 0 && e.KeyCode == Keys.Delete)
{
//处理逻辑
}

2.C#WinForm的密码输入框禁止粘贴和右键
private void LoginForm_Load(object sender, EventArgs e)
{
txtPassword.ContextMenu = new ContextMenu();
txtPassword.KeyPress += new KeyPressEventHandler(txtPassword_KeyPress);
}

    void txtPassword\_KeyPress(object sender, KeyPressEventArgs e)  
    \{  
        if ((int)e.KeyChar == 22)  
        \{  
            e.Handled = true;  
        \}  
    \}

拷贝文件夹(递归)

//要拷贝的文件路径

string dataFileName="";

//指定文件路径的目录信息

DirectoryInfo source = new DirectoryInfo(Path.GetDirectoryName(dataFileName));

//本地文件路径
string localFilePath = “C:\\temp\\“;
//本地文件目录
DirectoryInfo localDirectory = new DirectoryInfo(localFilePath);

///

/// 拷贝文件夹()
///

/// 要拷贝指定文件目录信息
/// 本地文件目录信息
private void CopyDirectory(DirectoryInfo source, DirectoryInfo destination)
{

  if (!destination.Exists) \{  
      destination.Create();  
  \}  
  FileInfo\[\] files = source.GetFiles();  
  foreach (FileInfo file in files)  
  \{  
      file.CopyTo(Path.Combine(destination.FullName, file.Name));  
  \}  
  DirectoryInfo\[\] dirs = source.GetDirectories();  
  foreach (DirectoryInfo dir in dirs)  
  \{                             
      string destinationDir = Path.Combine(destination.FullName, dir.Name);                           
      CopyDirectory(dir, new DirectoryInfo(destinationDir));  
  \}

}

获取资源文件（Xml）—要在同一命名空间下获取
XmlDocument myXml = new XmlDocument();
string fileName = “AdminClient.Resources.bpmsCodes.xml”;
Assembly asm = Assembly.GetExecutingAssembly();//读取嵌入式资源
Stream strm = asm.GetManifestResourceStream(fileName);
myXml.Load(strm);//读取指定的XML文档

5.设置窗体的初始位置
this.StartPosition = FormStartPosition.Manual; //必须先设置这个属性
this.Location = = new Point(this.pointX, this.pointY + this.InputControl.Height + 30);
