C#判断DLL文件是32位还是64位的示例代码

有些时候我们需要判断一下dll文件是32位还是64位，纠结该如何操作呢，下面小编通过实例代码给大家介绍下C#判断DLL文件是32位还是64位，感兴趣的朋友跟随小编一起看看吧

c#判断dll文件是32位还是64位，实例代码如下所示：

 using System; using System.IO; namespace GetDllVersionDemo { ///  ///     https://www.cnblogs.com/LifeDecidesHappiness/p/15711169.html ///     C#判断DLL文件是32位还是64位 ///     LDH @ 2021-12-20 /// 
 internal class Program { private static void Main() { Console.Title = "C#判断DLL文件是32位还是64位"; GetDll32Or64(); Console.ReadKey(); } private static void GetDll32Or64() { var dllPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"Dll\IBM.Data.Informix.dll"); var result = GetPeArchitecture(dllPath); //523 64位    267 32位 if (result == 523) Console.WriteLine(dllPath + "是【64】位的dll"); else if (result == 267) Console.WriteLine(dllPath + "是【32】位的dll"); else Console.WriteLine("执行错误！"); } ///  ///     获取dll文件是32位还是64位 ///     523 64位    267 32位 /// 
 /// dll文件路径 ///  public static ushort GetPeArchitecture(string dllFilePath) { ushort architecture = 0; try { using (var fStream = new FileStream(dllFilePath, FileMode.Open, FileAccess.Read)) { using (var bReader = new BinaryReader(fStream)) { if (bReader.ReadUInt16() == 23117) //check the MZ signature { fStream.Seek(0x3A, SeekOrigin.Current); //seek to e_lfanew. fStream.Seek(bReader.ReadUInt32(), SeekOrigin.Begin); //seek to the start of the NT header. if (bReader.ReadUInt32() == 17744) //check the PE\0\0 signature. { fStream.Seek(20, SeekOrigin.Current); //seek past the file header, architecture = bReader.ReadUInt16(); //read the magic number of the optional header. } } } } } catch { // ignored } // if architecture returns 0, there has been an error. return architecture; } } }
