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{/// <summary>/// 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/// </summary>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");elseConsole.WriteLine("执行错误！");} /// <summary>/// 获取dll文件是32位还是64位/// 523 64位 267 32位/// </summary>/// <param name="dllFilePath">dll文件路径</param>/// <returns></returns>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;}}}
