winform如何实现文件上传到指定路径 帖代码出来 谢谢

winform利用webclient 实现文件上传

1:浏览文件

OpenFileDialog open = new OpenFileDialog()

if (open.ShowDialog() == System.Windows.Forms.DialogResult.OK)

{

this.textBox1.Text = open.FileName

}

2：验证URI地址

string URi = "http://192.168.0.222//www/"

WebRequest myWebRequest = WebRequest.Create(URi)

myWebRequest.Timeout = -1

try

{

WebResponse webResponse = myWebRequest.GetResponse()

Stream webStream = webResponse.GetResponseStream()

webStream.Close()

//开a始º?上¦?传ä?

UploadFile(this.textBox1.Text, URi,true)

}

catch(WebException ex)

{

if (ex.Status == WebExceptionStatus.ProtocolError)

{

MessageBox.Show("服¤t务?器¡Â响¨¬应®|错䨪误¨®，ê?请?检¨¬查¨¦毕运和¨ª服¤t务?器¡Â连¢?接¨®是º?否¤?正y常¡ê！ê?")

}

if (ex.Status == WebExceptionStatus.Timeout)

{

MessageBox.Show("服¤t务?器¡Â超?时º¡À！ê?")

}

}

3：上传方法

private void UploadFile(string fileNamePath, string uriString, bool IsAutoRename)

{

/瞎数皮/第̨²一°?步?：êo获?取¨?要°a上¦?传ä?的Ì?文?件t信?息¡é

string fileName = fileNamePath.Substring(fileNamePath.LastIndexOf("\\")+1) //获?取¨?上¦?传ä?文?件t名?称?

string fileNameExt = fileName.Substring(fileName.LastIndexOf(".") + 1).ToLower()//文?件t后¨®缀Áo：êo小?写¡磨差ä

string newName = fileName

Guid gg = Guid.NewGuid()

if (IsAutoRename == true)

{

newName = gg.ToString() + fileName.Substring(fileName.LastIndexOf("."))//文?件t新?的Ì?名?称?

}

//第̨²二t部?：êo处ä|理¤¨ªURI地Ì?址¡¤

if (uriString.EndsWith("/") == false)

{

uriString = uriString + "/"

}

uriString = uriString + newName//匹£¤配?要°a上¦?传ä?文?件t：êoURI+文?件t名?

//第̨²三¨y部?：êo创ä¡ä建¡§wenClient实º¦Ì例¤y

WebClient client = new WebClient()

client.Credentials = CredentialCache.DefaultCredentials //设¦¨¨置?进?行D身¦¨ª份¤Y验¨¦证¡è的Ì?网ª?络?凭?证¡è

//第̨²四?部?：êo利¤?用®?流¢¡Â来¤¡ä实º¦Ì现?文?件t上¦?传ä?

FileStream fs = new FileStream(fileNamePath, FileMode.Open, FileAccess.ReadWrite)//要°a上¦?传ä?的Ì?文?件t穿ä?件t文?件t流¢¡Â

BinaryReader br = new BinaryReader(fs)//以°?二t进?制?方¤?式º?读¨¢取¨?

byte[] postArray = br.ReadBytes((int)fs.Length)//当Ì¡À前¡ã流¢¡Â写¡ä入¨?二t进?制?

Stream postStream = client.OpenWrite(uriString, "PUT")//向¨°指?定¡§的Ì?地Ì?址¡¤写¡ä入¨?数ºy据Y

try

{

if (postStream.CanWrite)

{

postStream.Write(postArray, 0, postArray.Length)

postStream.Close()

fs.Dispose()

MessageBox.Show("上¦?传ä?成¨¦功|！ê?")

}

else

{

postStream.Close()

fs.Dispose()

MessageBox.Show("上¦?传ä?失º¡ì败㨹！ê?")

}

}

catch(Exception ex)

{

postStream.Close()

fs.Dispose()

MessageBox.Show("上¦?传ä?文?件t异°¨¬常¡ê"+ex.Message)

throw ex

}

finally

{

postStream.Close()

fs.Dispose()

}

}

有很多方法

1）利用Socket（TCP或UDP）

2）利用WebClinet，采用HTTP上传如纳掘

3）利用FTP协议上传

4）局域网渣核内，利用共享文件夹也可以实现上传

……

具体采用哪种方法，茄谈取决于文件服务支持哪种协议
