谁能给个WPF使用mvvmLight模式的开源例子

Posted 2023-03-24

参考技术A 为何要做Viewmodel中定义控件呢?在Viewmodel定义PasswordBox的需要获得的属性,如Text,然后在view中应用绑定就可以了。

谁能给个C语言socket 通信，用UDP协议的代码例子。。

使用#include<winsock2.h>库中的socket，学习学习。本人不懂，问题有疑问的话，留言！

我的是包含的#include <sys/socket.h>，参考一下吧
<udp_client.c>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <sys/socket.h>
#include <arpa/inet.h>

int main(void)

int sfd; char buf[1024]; int n, i;
struct sockaddr_in serv_addr, cli_addr;
socklen_t len;

sfd = socket(AF_INET, SOCK_DGRAM, 0);

memset(&serv_addr, 0, sizeof(serv_addr));
serv_addr.sin_family = AF_INET;
serv_addr.sin_port = htons(8000);
inet_pton(AF_INET, "192.168.0.36", &serv_addr.sin_addr.s_addr);

while(1)
if(fgets(buf, 1024, stdin) == NULL)
break;
sendto(sfd, buf, strlen(buf), 0, (struct sockaddr *)&serv_addr, sizeof(serv_addr));
n = recvfrom(sfd, buf, 1024, 0, NULL, NULL);
write(STDOUT_FILENO, buf, n);

close(sfd);

return 0;


<udp_server.c>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h>
#include <arpa/inet.h>

int main(void)

int sfd; char buf[1024]; int n, i;
struct sockaddr_in serv_addr, cli_addr;
socklen_t len;

sfd = socket(AF_INET, SOCK_DGRAM, 0);

memset(&serv_addr, 0, sizeof(serv_addr));
serv_addr.sin_family = AF_INET;
serv_addr.sin_port = htons(8000);
serv_addr.sin_addr.s_addr = htonl(INADDR_ANY);

bind(sfd, (struct sockaddr *)&serv_addr, sizeof(serv_addr));

while(1)
len = sizeof(cli_addr);
n = recvfrom(sfd, buf, 1024, 0, (struct sockaddr *)&cli_addr, &len);
for(i = 0; i < n; i++)
buf[i] = toupper(buf[i]);
sendto(sfd, buf, n, 0, (struct sockaddr *)&cli_addr, len);

close(sfd);

return 0;
