117笔记问答要使用C# FluentFTP库上传文件，首先确保已经安装了FluentFTP NuGet包。然后，按照以下步骤操作：
- 引入必要的命名空间：
using System; using System.IO; using FluentFTP;
- 创建一个FtpClient对象并连接到FTP服务器：
string host = "your_ftp_host"; int port = 21; // 默认的FTP端口是21 string username = "your_username"; string password = "your_password"; FtpClient client = new FtpClient(host, port, username, password); client.EncryptionMode = FtpEncryptionMode.Explicit; // 设置加密模式为显式 client.Connect();
- 检查连接是否成功：
if (!client.IsConnected)
{
Console.WriteLine("Failed to connect to FTP server.");
return;
}
- 使用
UploadFile方法上传文件：
string localFilePath = @"C:\path\to\your\local\file.txt"; // 本地文件路径
string remoteFilePath = "/remote/path/file.txt"; // FTP服务器上的目标路径
bool success = client.UploadFile(localFilePath, remoteFilePath);
if (success)
{
Console.WriteLine("File uploaded successfully.");
}
else
{
Console.WriteLine("Failed to upload file.");
}
- 断开与FTP服务器的连接：
client.Disconnect();
完整的示例代码如下：
using System;
using System.IO;
using FluentFTP;
namespace FtpUploadExample
{
class Program
{
static void Main(string[] args)
{
string host = "your_ftp_host";
int port = 21;
string username = "your_username";
string password = "your_password";
FtpClient client = new FtpClient(host, port, username, password);
client.EncryptionMode = FtpEncryptionMode.Explicit;
client.Connect();
if (!client.IsConnected)
{
Console.WriteLine("Failed to connect to FTP server.");
return;
}
string localFilePath = @"C:\path\to\your\local\file.txt";
string remoteFilePath = "/remote/path/file.txt";
bool success = client.UploadFile(localFilePath, remoteFilePath);
if (success)
{
Console.WriteLine("File uploaded successfully.");
}
else
{
Console.WriteLine("Failed to upload file.");
}
client.Disconnect();
}
}
}
请根据实际情况替换your_ftp_host、your_username、your_password和本地文件路径。运行此代码后，文件将从本地上传到FTP服务器。
