visual studio 2015，界面越来越漂亮了。
比起swift和python啥的，还是c#外观上更像java，windows的界面编程，wpf的方式跟android等编程也蛮像，声明式的界面定义，界面和controller类当然绑定，总之玩着很爽就是了。
现在在想的问题是想个啥主题做着……
下面的代码是学习关键点时练的，老规矩，界面交互+web请求+数据库访问——

{//进行web请求
HttpWebRequest httpRequest = (HttpWebRequest)WebRequest.Create("http://427studio.net/api/blog");
httpRequest.Timeout = 2000;
httpRequest.Method = "GET";
HttpWebResponse httpResponse = (HttpWebResponse)httpRequest.GetResponse();
StreamReader sr = new StreamReader(httpResponse.GetResponseStream(), System.Text.Encoding.GetEncoding("utf-8"));
string result = sr.ReadToEnd();
result = result.Replace("\r", "").Replace("\n", "").Replace("\t", "");
int status = (int)httpResponse.StatusCode;
sr.Close();//解析json
List<Person> ps = JSON.parse<List<Person>>(result);
foreach (Person p in ps)
{
Console.WriteLine(p.title);
}
jsonCount.Content = "js数组长度：" + ps.Count();//数据库连接
string str = "Server=那啥;User ID=那啥;Password=那啥;Database=那啥;CharSet=那啥;";
MySqlConnection conn = new MySqlConnection(str);//实例化链接
conn.Open();//开启连接
string strcmd = "select id, name from admin_user";
MySqlCommand cmd = new MySqlCommand(strcmd, conn);
MySqlDataReader reader = cmd.ExecuteReader();
int rowCount = 0;
while (reader.Read())
{
String title = reader.GetString("name");
//Console.WriteLine(title);rowCount++;
}
dbCount.Content = "数据库记录行数：" + rowCount;
reader.Close();
conn.Close();//文件系统
FileStream fs = new FileStream("test.txt", FileMode.OpenOrCreate);
StreamWriter sw = new StreamWriter(fs);
sw.Write("由wpf程序写入！");
sw.Close();
}
