C# 实现FTP上传资料的示例
1.通过用FTP进行上传文件，首先要实现建立FTP连接，一般建立FTP连接，需要知道FTP配置有关的信息。一般要在Bean中建立一个ServiceFileInfo.cs文件进行记录，一般需要FTP地址、登录用户名和登录密码。然后通过其他页面进行访问读取。代码样式如下：
classServiceFileInfo
{
//service1
publicstaticstringtxtFilePath=@"ftp://12.128.128.01/FileName/";
//userid&password
publicstaticstringtxtUID="username";
publicstaticstringtxtPWD="password";
}
2.通过主方法读取Bean文件下面的的ServiceFileInfo.cs文件的信息，去实现建立FTP连接。这里还需要清楚的知道你上传文件的路径(Path)和文件名称(FileName)。根据这些信息主方法去调用写着Bean中的另外一个ftpOperation.cs文件(这个.cs文件中主要写一些关于FTP的操作方法)，进行FTP访问操作。
- 主方法调用FTP操作代码
ExecutionResultexeRes=this.ftpOperation.UploadFile(textFilePath,txtUID,txtPWD,Path+"/"+FileName+".txt");//.txt为文件的后缀名
- Bean文件中ftpOperation.cs文件关于FTP操作的方法
publicExecutionResultUploadFile(stringvIMSPath,stringvUID,stringvPassword,stringvLocalPath)
{
ExecutionResultresult=newExecutionResult();
result=connectState(vIMSPath,vUID,vPassword,vLocalPath);//调用下面代码方法
if(result.Status)
{
File.Delete(vLocalPath);
}
returnresult;
}
- connectState()方法
publicstaticExecutionResultconnectState(stringvIMSPath,stringvUID,stringvPassword,stringfileName)
{
stringoperater="";
boolFlag=false;
ExecutionResultresult;
result=newExecutionResult();
lock(lockObj)
{
try
{
operater="ConnettoFTP";
FTPOperationftp=newFTPOperation(newUri(vIMSPath),vUID,vPassword);
operater="Uploadfile";
Flag=ftp.UploadFile(fileName,Path.GetFileName(fileName),true);
if(Flag)
{
result.Status=true;
result.Message="SendtoserverOK";
}
}
catch(Exceptionex)
{
result.Status=false;
result.Anything="Mail";
result.Message=operater+":"+ex.Message;
}
}
returnresult;
}
- UploadFile()方法
publicboolUploadFile(stringLocalFullPath,stringRemoteFileName,boolOverWriteRemoteFile)
{
boolresult;
try
{
boolflag=!this.IsValidFileChars(RemoteFileName)||!this.IsValidFileChars(Path.GetFileName(LocalFullPath))||!this.IsValidPathChars(Path.GetDirectoryName(LocalFullPath));
if(flag)
{
thrownewException("非法文件名或目录名!");
}
boolflag2=File.Exists(LocalFullPath);
if(!flag2)
{
thrownewException("本地文件不存在!");
}
FileStreamfileStream=newFileStream(LocalFullPath,FileMode.Open,FileAccess.Read);
byte[]array=newbyte[fileStream.Length];
fileStream.Read(array,0,(int)fileStream.Length);
fileStream.Close();
result=this.UploadFile(array,RemoteFileName,OverWriteRemoteFile);
}
catch(Exceptionex)
{
this.ErrorMsg=ex.ToString();
throwex;
}
returnresult;
}
publicboolUploadFile(byte[]FileBytes,stringRemoteFileName)
{
boolflag=!this.IsValidFileChars(RemoteFileName);
if(flag)
{
thrownewException("非法文件名或目录名!");
}
returnthis.UploadFile(FileBytes,RemoteFileName,false);
}
publicboolUploadFile(byte[]FileBytes,stringRemoteFileName,boolOverWriteRemoteFile)
{
boolresult;
try
{
boolflag=!this.IsValidFileChars(RemoteFileName);
if(flag)
{
thrownewException("非法文件名！");
}
boolflag2=!OverWriteRemoteFile&&this.FileExist(RemoteFileName);
if(flag2)
{
thrownewException("FTP服务上面已经存在同名文件！");
}
this.Response=this.Open(newUri(this.Uri.ToString()+RemoteFileName),"STOR");
StreamrequestStream=this.Request.GetRequestStream();
MemoryStreammemoryStream=newMemoryStream(FileBytes);
byte[]array=newbyte[1024];
intnum=0;
for(;;)
{
intnum2=memoryStream.Read(array,0,array.Length);
boolflag3=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(Exceptionex)
{
this.ErrorMsg=ex.ToString();
throwex;
}
returnresult;
}
