1、壓縮某個指定目錄下日志，將日志壓縮到CompressionDirectory文件夾中，並清除原來未壓縮日志。
#region 壓縮logs目錄下日志
public static void CompresslogDic()

FileInfo[] bipLog = logsDic.GetFiles();

for (int i = 0; i < bipLog.Length; i++)
{
if (bipLog[i].Name.Substring(bipLog[i].Name.Length - 3) != "zip")
{
logsInOneDay.Add(bipLog[i]);
}
}
if (logsInOneDay.Count > 0)

}
string compressFileName = dt.ToString("yyyy-MM-dd");
