using System.Threading.Tasks;

namespace Calculate_Tiff_page_with_BitMiracle.LibTiff.Net
{
class Program
{
static void Main(string[] args)
{
string path = @"C:\Users\owlin\Downloads\test.tif";
using (Tiff image = Tiff.Open(path, "r"))
{
Console.WriteLine(CalculatePageNumber(image));
Console.ReadLine();
}
}
private static int CalculatePageNumber(Tiff image)
{
int pageCount = 0;
do
{
++pageCount;
} while (image.ReadDirectory());

return pageCount;
}
}

}

[C#]FTP上下傳檔案，使用WinSCP

用NuGet下載WinSCP .Net Assembly，Version：5.7.4
官方網頁

原始碼如下

using System;

static string ftpUploadUrl = "IP或domain"; //不可以有ftp:\
static string ftpAccount = "Ftp帳號";
static string ftpPassword = "Ftp密碼";
static string localPath = @"D:\temp\";
static string remotePath = "/work/";

static void Main(string[] args)
{
Download();
Upload();
}
private static void Upload()
{
try
{
SessionOptions sessionOptions = new SessionOptions
{
Protocol = Protocol.Ftp,
HostName = ftpUploadUrl,
UserName = ftpAccount,
Password = ftpPassword,
};

using (Session session = new Session())
{
// Connect
session.Open(sessionOptions);

// Upload files
TransferOptions transferOptions = new TransferOptions();
transferOptions.TransferMode = TransferMode.Binary;

TransferOperationResult transferResult;

transferResult = session.PutFiles(localPath + "*", remotePath, true, transferOptions); //*表示全部檔案

// Throw on any error
transferResult.Check();
// Print results
foreach (TransferEventArgs transfer in transferResult.Transfers)
{
Console.WriteLine("Upload of {0} succeeded", transfer.FileName);
}
session.Close();
}
}
catch (Exception e)
{
throw e;
}
}

private static void Download()
{
try
{
SessionOptions sessionOptions = new SessionOptions
{
Protocol = Protocol.Ftp,
HostName = ftpUploadUrl,
UserName = ftpAccount,
Password = ftpPassword,
};

using (Session session = new Session())
{
// Connect
session.Open(sessionOptions);

// Upload files
TransferOptions transferOptions = new TransferOptions();
transferOptions.TransferMode = TransferMode.Binary;

TransferOperationResult transferResult;

transferResult = session.GetFiles(remotePath + "*", localPath, false, transferOptions);//*表示全部檔案

// Throw on any error
transferResult.Check();
// Print results
foreach (TransferEventArgs transfer in transferResult.Transfers)
{
Console.WriteLine("Download of {0} succeeded", transfer.FileName);

[C#]複寫SignalR OnConnected、OnDisconnected、OnReconnected

若要複寫SignalR Hub的OnConnected、OnDisconnected、OnReconnected

JavaScript

var chat = $.connection.chatHub;
// Need at least one callback for events to be raised on the hub
chat.client.void = function () { };//這行非加不可否則不會自動執行Server的OnConnected跟OnDisconnected
// Start the connection.
$.connection.hub.start();
