c＃编码的解释 [英] explanation for c# coding

问题描述

我需要逐行解释以下编码。请尽快请求发送解决方案。

I need line by line explanation for following codings.kindly request to send the solution as early as possible.

namespace RunTimeDefenceAgainstCodeInjectionAttack
{
   static class genModule
   {
      public static SqlConnection con = 
           new SqlConnection("server=.;uid=sa;database=RunTimeDefenceAgainstCodeInjectionAttack");
      
      //public con As New OleDbConnection("Server=.;database=OnFairness;user id=sa;password=") 
      public static SqlCommand cmd = new SqlCommand("", con);
      //public static bool startmonitor = false;
   }
}

推荐答案

// Identify the namespace for this code module
namespace RunTimeDefenceAgainstCodeInjectionAttack
{
   // Create a static class with the name genModule
   static class genModule
   {
      // Create a SqlConnection object to connection to the "RunTimeDefenceAgainstCodeInjectionAttack" database.
      public static SqlConnection con =
           new SqlConnection("server=.;uid=sa;database=RunTimeDefenceAgainstCodeInjectionAttack");

      //This line is commented out and will not be compiled.
      //public con As New OleDbConnection("Server=.;database=OnFairness;user id=sa;password=")

      // Create a SqlCommand object that can be used to generate and execute queries against the connection "con" which was created above.
      public static SqlCommand cmd = new SqlCommand("", con);

      //This line is commented out and will not be compiled.
      //public static bool startmonitor = false;
   }
}

在连接字符串上：

On the connection string:

"server=.;uid=sa;database=RunTimeDefenceAgainstCodeInjectionAttack"

sever =。 表示服务器在本地计算机上。



uid = sa 意味着用户ID是 sa ，这也意味着您没有使用类似Windows身份验证的东西，而是使用数据库身份验证



database = RunTimeDefenceAgainstCodeInjectionAttack 表示指定的数据库名称是 RunTimeDefenceAgainstCodeInjectionAttack



要查看所有连接字符串属性的说明，请转到 http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.connectionstring.aspx [ ^ ]

The sever=. means that the server is on the local machine.

The uid=sa means that the user id is sa, which also mean that you are not using something like Windows authentication, but using the database authentication

The database=RunTimeDefenceAgainstCodeInjectionAttack means that the database name that is specified is RunTimeDefenceAgainstCodeInjectionAttack

To see description of all connection string attributes goto http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.connectionstring.aspx[^]

private static List MapList(DataTable dt)
{
	List list = new List();

	FieldInfo[] fields = typeof(T).GetFields();
	T t = Activator.CreateInstance();

	foreach (DataRow dr in dt.Rows)
	{
		foreach (FieldInfo fi in fields)
			fi.SetValueDirect(__makeref(t), dr[fi.Name]);

		list.Add(t);
	}

	return list;
}

任何人都可以向我解释上面的代码..

Can anyone please explain me the above code..
