好的。所以我正在使用 Visual Studios 2010 -> Visual C++ 和 .NET Framework（Windows 窗体应用程序），当我尝试使用 hashlib++ 对字符串进行哈希处理时，出现多个 LNK 错误。

这是 hashlib++：http ://hashlib2plus.sourceforge.net/

这是我的哈希代码：

//I have more Includes but according to http://hashlib2plus.sourceforge.net/example.html these are the only ones required for hashlib++ so these are the ones i am putting on display.
#include <string>
#include <iostream>
#include <hashlibpp.h>

//I skipped adding namespaces to my display code

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {

                 try{
                     String^ atmp_user = textBox1->Text;
                     String^ user = (myReader->GetString(1));//Connecting to MySQL Databases and grabbing usernames
                     String^ atmp_pass = textBox2->Text;
                     String^ pass = (myReader->GetString(2));
                     atmp_pass->ToLower();//LowerCase
                     atmp_user->ToLower();
                     String^ total1 = gcnew String(atmp_user+atmp_pass);

                     string totala;

                     MarshalString(total1, totala);//Converting String^ to an std::string

                     hashwrapper *myWrapper = new sha1wrapper();//SHA1 code begins

         string hash1 = myWrapper->getHashFromString(totala);

 delete myWrapper;//SHA1 code ends

                     if(atmp_user == user && hash1 == pass){
                         textBox1->Text = ("It worked!");
                     }
                     }
                 } catch(Exception^ex) {
                     MessageBox::Show(ex->Message);
                 }
         }

这是我的错误日志：

任何帮助将不胜感激。:) 在过去的几天里，我一直在努力创建一个安全的登录脚本。我到处都遇到 LNK 错误。:\

解决了。我不得不关闭预编译的头文件。
