C#實作FTP上傳資料
1.通過用FTP進行上傳檔案,首先要實作建立FTP連接配接,一般建立FTP連接配接,需要知道FTP配置有關的資訊。一般要在Bean中建立一個ServiceFileInfo.cs檔案進行記錄,一般需要FTP位址、登入使用者名和登入密碼。然後通過其他頁面進行通路讀取。代碼樣式如下:
class ServiceFileInfo
{
// service1
public static string txtFilePath = @"ftp://12.128.128.01/FileName/";
//userid & password
public static string txtUID = "username";
public static string txtPWD = "password";
}
2.通過主方法讀取Bean檔案下面的的ServiceFileInfo.cs檔案的資訊,去實作建立FTP連接配接。這裡還需要清楚的知道你上傳檔案的路徑(Path)和檔案名稱(FileName)。根據這些資訊主方法去調用寫着Bean中的另外一個ftpOperation.cs 檔案(這個.cs檔案中主要寫一些關于FTP的操作方法),進行FTP通路操作。
- 主方法調用FTP操作代碼
ExecutionResult exeRes = this.ftpOperation.UploadFile(textFilePath, txtUID, txtPWD, Path + "/" + FileName + ".txt");//.txt為檔案的字尾名
- Bean檔案中ftpOperation.cs檔案關于FTP操作的方法
public ExecutionResult UploadFile(string vIMSPath, string vUID, string vPassword, string vLocalPath)
{
ExecutionResult result = new ExecutionResult();
result = connectState(vIMSPath, vUID, vPassword, vLocalPath);//調用下面代碼方法
if (result.Status)
{
File.Delete(vLocalPath);
}
return result;
}
connectState()方法
public static ExecutionResult connectState(string vIMSPath, string vUID, string vPassword, string fileName)
{
string operater = "";
bool Flag = false;
ExecutionResult result;
result = new ExecutionResult();
lock (lockObj)
{
try
{
operater = "Connet to FTP";
FTPOperation ftp = new FTPOperation(new Uri(vIMSPath), vUID, vPassword);
operater = "Upload file";
Flag = ftp.UploadFile(fileName, Path.GetFileName(fileName), true);
if (Flag)
{
result.Status = true;
result.Message = "Send to server OK";
}
}
catch (Exception ex)
{
result.Status = false;
result.Anything = "Mail";
result.Message = operater + ":" + ex.Message;
}
}
return result;
}
- UploadFile()方法
public bool UploadFile(string LocalFullPath, string RemoteFileName, bool OverWriteRemoteFile)
{
bool result;
try
{
bool flag = !this.IsValidFileChars(RemoteFileName) || !this.IsValidFileChars(Path.GetFileName(LocalFullPath)) || !this.IsValidPathChars(Path.GetDirectoryName(LocalFullPath));
if (flag)
{
throw new Exception("非法檔案名或目錄名!");
}
bool flag2 = File.Exists(LocalFullPath);
if (!flag2)
{
throw new Exception("本地檔案不存在!");
}
FileStream fileStream = new FileStream(LocalFullPath, FileMode.Open, FileAccess.Read);
byte[] array = new byte[fileStream.Length];
fileStream.Read(array, 0, (int)fileStream.Length);
fileStream.Close();
result = this.UploadFile(array, RemoteFileName, OverWriteRemoteFile);
}
catch (Exception ex)
{
this.ErrorMsg = ex.ToString();
throw ex;
}
return result;
}
public bool UploadFile(byte[] FileBytes, string RemoteFileName)
{
bool flag = !this.IsValidFileChars(RemoteFileName);
if (flag)
{
throw new Exception("非法檔案名或目錄名!");
}
return this.UploadFile(FileBytes, RemoteFileName, false);
}
public bool UploadFile(byte[] FileBytes, string RemoteFileName, bool OverWriteRemoteFile)
{
bool result;
try
{
bool flag = !this.IsValidFileChars(RemoteFileName);
if (flag)
{
throw new Exception("非法檔案名!");
}
bool flag2 = !OverWriteRemoteFile && this.FileExist(RemoteFileName);
if (flag2)
{
throw new Exception("FTP服務上面已經存在同名檔案!");
}
this.Response = this.Open(new Uri(this.Uri.ToString() + RemoteFileName), "STOR");
Stream requestStream = this.Request.GetRequestStream();
MemoryStream memoryStream = new MemoryStream(FileBytes);
byte[] array = new byte[1024];
int num = 0;
for (;;)
{
int num2 = memoryStream.Read(array, 0, array.Length);
bool flag3 = num2 == 0;
if (flag3)
{
break;
}
num += num2;
requestStream.Write(array, 0, num2);
}
requestStream.Close();
this.Response = (FtpWebResponse)this.Request.GetResponse();
memoryStream.Close();
memoryStream.Dispose();
FileBytes = null;
result = true;
}
catch (Exception ex)
{
this.ErrorMsg = ex.ToString();
throw ex;
}
return result;
}
