如果 (!textBox_fileName.Text.Trim()。等于(“” ))
{
字符串 的loadFile = textBox_fileName.Text.Trim();
字符串 文件名= loadFile.Substring(loadFile.LastIndexOf(“\”)+1,loadFile.Length - 1 - loadFile.LastIndexOf(“ \”));
字符串 urlStr = @ “http://127.0.0.1/test/UploadFile.aspx?name=” +文件名;
UploadFileBinary(的loadFile,urlStr);
}
其他
{
字符串 alStr = “您还没有选择文件” ;
MessageBox.Show(alStr, “ 系统提示” ,MessageBoxButtons.OK,MessageBoxIcon.Exclamation,MessageBoxDefaultButton.Button1);
}C#代码
公共无效 UploadFileBinary(字符串 LOCALFILE, 字符串 的uploadURL)
{
尝试
{
RDR的FileStream = 新 的FileStream(LOCALFILE,FileMode.Open);
字节[] = INDATA 新字节[4096];
INT totbytes = 0;
MemoryStream的POSTDATA = 新 的MemoryStream();
INT 读取动作= rdr.Read(INDATA,0,inData.Length);
而 (读取动作> 0)
{
postData.Write(INDATA,0,读取动作);
读取动作= rdr.Read(INDATA,0,inData.Length);
totbytes + =读取动作;
}
rdr.Close();
postData.Position = 0;
HttpWebRequest的REQ =(HttpWebRequest的)WebRequest.Create(的uploadURL);
req.Method = “POST” ;
req.ContentLength =(长)postData.Length;
使用 (流S = req.GetRequestStream())
{
s.Write(postData.ToArray(),0,(INT )postData.Length);
postData.Close();
}
WebResponse类RESP = req.GetResponse();
System.Text.Encoding resEncoding = System.Text.Encoding.GetEncoding(“UTF-8”); //接收的编码
StreamReader的读者= 新 的StreamReader(resp.GetResponseStream(),resEncoding);
字符串 味精= reader.ReadToEnd();
reader.Close();
resp.Close();
如果 (MSG!= 空 && msg.Equals( “ 成功” ))
{
MessageBox.Show( “ 图片上传成功” ,“提示” );
}
}
赶上 (异常前)
{
//字符串exContent;
// exContent = ex.ToString();
MessageBox.Show( “ 上传失败网络出现异常或者图片文件已经存在!” ,“提示” );
}
}
.NET接收图片附件文件
C#代码
Response.ContentEncoding = Encoding.GetEncoding(“UTF-8” );
//在此处放置用户代码以初始化页面
字节[]海图= 零;
串ls_name;
如果 (Request.ServerVariables [ “REQUEST_METHOD” ]的ToString()。ToUpper的()== “POST” )
{
海图= Request.BinaryRead(Request.ContentLength);
//获取文件名称
ls_name =的Request.QueryString [ “名” ];
//字符串picName = DateTime.Now.Ticks.ToString()+符“.gif”;
//字符串picName = DateTime.Now.Ticks.ToString()+“.JPG”;
STM的FileStream = 新 的FileStream(使用Server.Mappath(一个“UploadFile /” + ls_name),System.IO.FileMode.CreateNew);
stm.Write(海图,0,(INT )theData.Length);
stm.Close();
的Response.Write( “ 成功” );
}
其他
{
的Response.Write( “ 错误” );
}
每个人都需要一台速度更快、更稳定的 PC。随着时间的推移,垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是,许多工具可以让 Windows 保持平稳运行。
