最近由于项目需要实现c#提交文字及数据至服务器,因此研究了一下c# php数据传送;
下面用一个示例来演示,c# post文字+图片 ,php端接收;
post提交数据核心代码(post数据提交)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Drawing;
using System.Web;
using System.Net;
namespace postpic
{
class postClass
{
///
/// 向服务器post文字和图片
///
///url
///用户名
///密码
///头像地址
/// 返回服务器返回值
public string post(string url,string userName, string userPwd, string jpegPath)
{
//将图片转化为byte[]再转化为string
string array = Convert.ToBase64String(imageToByteArray(jpegPath));
//构造post提交字段
string para = name=+userName+&pwd=+userPwd+&head=+HttpUtility.UrlEncode(array);
#region HttpWebRequest写法
HttpWebRequest httpWeb = (HttpWebRequest)WebRequest.Create(url);
httpWeb.Timeout = 20000;
httpWeb.Method = POST;
httpWeb.ContentType = application/x-www-form-urlencoded;
byte[] bytePara = Encoding.ASCII.GetBytes(para);
using (Stream reqStream = httpWeb.GetRequestStream())
{
//提交数据
reqStream.Write(bytePara, 0, para.Length);
}
//获取服务器返回值
HttpWebResponse httpWebResponse = (HttpWebResponse)httpWeb.GetResponse();
Stream stream = httpWebResponse.GetResponseStream();
StreamReader streamReader = new StreamReader(stream, Encoding.GetEncoding(utf-8));
//获得返回值
string result = streamReader.ReadToEnd();
stream.Close();
#endregion
//将服务器返回值返回
return result;
}
///
/// 图片转为Byte字节数组
///
///路径
/// 字节数组
private byte[] imageToByteArray(string FilePath)
{
using (MemoryStream ms = new MemoryStream())
{
using (Image imageIn = Image.FromFile(FilePath))
{
using (Bitmap bmp = new Bitmap(imageIn))
{
bmp.Save(ms, imageIn.RawFormat);
}
}
return ms.ToArray();
}
}
}
}
一、c#客户端
为了方便说明,我直接简化了,一个提交按钮就好了。
二、需要提交的图片
该图片存放在俺的E盘根目录下面~~~~~(贴吧随便抓的一张图片)
path = @E:head.jpg;
三、php服务端
接收图片后存放至,path = @C:Loginlog;

c#端代码:
c#界面简单代码~~~~~(该代码可略过~~~~~)
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace postpic
{
public partial class postFrom : Form
{
public postFrom()
{
InitializeComponent();
}
///
/// 提交按钮,提交post数据
///
///
///
private void btnpost_Click(object sender, EventArgs e)
{
//postClass为数据提交类
postClass ps = new postClass();
string url = @http://localhost/login.php;
string name = DooZn;
string pwd = a12345;
string jpegPath = @E:head.jpg;
//提交数据
string value = ps.post(url,name,pwd,jpegPath);
//value为服务器返回值
if (value.Contains(1))
{
MessageBox.Show(登陆成功.);
}
else if (value.Contains(0))
{
MessageBox.Show(登陆失败.);
}
else
{
MessageBox.Show(未知错误.);
}
}
}
}
