Common namespace locations

When writing a class file, you don't want to introduce the namespace unless you need some methods. Well, you cannot figure it out. record it. Multiple records are used.

Note the following to add a project reference system. Web. dll

Use using system. configuration; these require using system. configuration; namespaces

Public void break (string strinfo)
{
System. web. httpcontext. current. response. write ("<SCRIPT> alert (\ '" + strinfo + "\'); history. back (); </SCRIPT> ");
System. Web. httpcontext. Current. response. End ();
}

Userjudge2 = system. Text. encoding. Default. getbytecount (STR );

Stringbuilder sb = new stringbuilder ();

SB. append ("××× )");

 

Response

System. web. httpcontext. current. response. write ("<SCRIPT> alert (\ '" + errinfo + "\'); history. back (); <"+"/SCRIPT> ");

 

Server. mappath

Configurationsettings. deleettings ["ac_dbpath"]);

MD5

System. Web. Security. formsauthentication. hashpasswordforstoringinconfigfile (STR, "MD5 ")

Configurationsettings

System. configuration. configurationsettings. receivettings ["mailfrom"];

Servervariables (hot, I found it for half a day.)

System. Collections. Specialized. namevaluecollection servervariables = system. Web. httpcontext. Current. Request. servervariables;
Response. Write (servervariables ["http_referer"]);
