一、获取运行文件目录相关：
1、//使用AppDomain获取当前目录
string dir = AppDomain.CurrentDomain.BaseDirectory;
2、//使用path获取当前应用程序集的执行的上级目录
string dir1 = Path.GetFullPath("..");
3、//使用path获取当前应用程序集的执行的上上级级目录
string dir2 = Path.GetFullPath(@"..//..");
4、//程序自带(常用)
Application.StartupPath
二、进程相关：
1、获取进程并关闭进程
Process[] p = Process.GetProcessesByName(clientName);
foreach (Process ps in p)
{
ps.Kill();
}
2、根据路径打开进程
ProcessStartInfo pinfo = new ProcessStartInfo();
pinfo.UseShellExecute = true;
pinfo.FileName = string.Format(@"{0}\{1}\{2}", Application.StartupPath,clientName, fileName); //程序路径
//启动进程
Process p = Process.Start(pinfo);
三、序列化与反序列化：
1、json序列化与反序列化
string jsonMsg=JsonConvert.SerializeObject(resetPosition); //序列化对象为json
JObject joStatus = (JObject)JsonConvert.DeserializeObject(jsonMsg); //反序列化为JObject泛型对象
AlarmReportModel alarmReportModel = JsonConvert.DeserializeObject<AlarmReportModel>(jsonMsg); //反序列化为具体对象
2、xml序列化与反序列化
四、开机自启动：
RegistryKey R_local = Registry.CurrentUser;//RegistryKey R_local = Registry.CurrentUser;
RegistryKey R_run = R_local.CreateSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run");
R_run.SetValue("自动升级软件", Application.ExecutablePath);
R_run.Close();
R_local.Close();
三、压缩、解压
1、
System.IO.Compression.ZipFile.CreateFromDirectory(@"e:\test", @"e:\test\test.zip"); //压缩
System.IO.Compression.ZipFile.ExtractToDirectory(@"e:\test\test.zip", @"e:\test"); //解压
2、格式支持rar 7zip, zip, tar, tzip和bzip2格式，引用 using SharpCompress.dll
using (Stream stream = File.OpenRead(@"C:\Code\sharpcompress.rar"))
{
var reader = ReaderFactory.Open(stream);
while (reader.MoveToNextEntry())
{
if (!reader.Entry.IsDirectory)
{
Console.WriteLine(reader.Entry.FilePath);
reader.WriteEntryToDirectory(@"C:\temp");
}
}
}
3、引用 using ICSharpCode.SharpZipLib.Zip
/// <summary>
/// 压缩单个文件
/// </summary>
/// <param name="fileToZip">要压缩的文件</param>
/// <param name="zipedFile">压缩后的文件全名</param>

/// <param name="blockSize">分块大小</param>

{
if (!System.IO.File.Exists(fileToZip))//如果文件没有找到，则报错
{
throw new FileNotFoundException("The specified file " + fileToZip + " could not be found. Zipping aborderd");
}
FileStream streamToZip = new FileStream(fileToZip, FileMode.Open, FileAccess.Read);
FileStream zipFile = File.Create(zipedFile);
ZipOutputStream zipStream = new ZipOutputStream(zipFile);
ZipEntry zipEntry = new ZipEntry(fileToZip);
zipStream.PutNextEntry(zipEntry);
zipStream.SetLevel(compressionLevel);
byte[] buffer = new byte[blockSize];
int size = streamToZip.Read(buffer, 0, buffer.Length);
zipStream.Write(buffer, 0, size);
try
{
while (size < streamToZip.Length)
{
int sizeRead = streamToZip.Read(buffer, 0, buffer.Length);
zipStream.Write(buffer, 0, sizeRead);
size += sizeRead;
}
}
catch (Exception ex)
{
GC.Collect();
throw ex;
}
zipStream.Finish();
zipStream.Close();
streamToZip.Close();
GC.Collect();
}

continue;

//建立下面的目录和子目录
Directory.CreateDirectory(directoryName);
//记录导出的文件
unzipFiles.Add(unzippath + theEntry.Name);
FileStream streamWriter = File.Create(unzippath + theEntry.Name);
