本文介绍了一种使用C#调用Windows API函数来读取Win32 DLL文件中的字符串资源的方法。通过具体示例展示了如何加载DLL、获取指定ID的字符串资源并显示结果。

在C#中，通过Windows API函数读取标准的Win32 DLL文件中的字符串资源

下面的代码以读取 user32.dll 文件中的ＩＤ号为712的字符串资源。

如果代码运行正常的话，应该可以看到

        public static extern int LoadString(IntPtr hLib, uint resID, byte[] buf, int bufSize);

        [STAThread]
        static void Main(string[] args) {

            if(hDll == IntPtr.Zero){
                MessageBox.Show("Can't load library!");
                return;
            }
            byte[] sb=new byte[1024];
            int ret=0;
            ret=LoadString(hDll,712,sb,1025);
            if(ret == 0){
                MessageBox.Show("String resource 712 is not found!");
                FreeLibrary(hDll);
                return;
            }
            MessageBox.Show("String Resource 100: " +Encoding.Unicode.GetString(sb).Replace("/0",""));
            FreeLibrary(hDll);
            return;
        }
    }
