Assembly resolve(自定义加载指定目录的程序集)

 默认情况下项目引用的dll都需要放在跟主程序相同的目录下，当项目引用的dll越来越多，则会显得凌乱。

这时可以通过AssemblyResolve来处理这件事情。

AppDomain.CurrentDomain.AssemblyResolve += OnCurrentDomainAssemblyResolve;
           

private Assembly OnCurrentDomainAssemblyResolve(object sender, ResolveEventArgs args)
           

if(string.IsNullOrWhiteSpace(args.Name))
           

return null;
           

}
           

string[] assemblyNameSplits = args.Name.Split(',');
           

if(assemblyNameSplits.Length == 0)
           

return null;
           

}
           

string name = asemblyNameSplits[0];
           

if(asemblyNameSplits.Length==3)
           

string name2= asemblyNameSplits[2];
           

if(name.EndsWith(".resources") && name2.EndsWith("neutral"))
           

return null;
           

}
           

else
           

return LoadAssembly(name);
           

}
           

}
           

return LoadAssembly(name);
           

}
           

private Assembly LoadAssembly(string name)
           

if(assemblyLoadedDic.ContainsKey(name))
           

return assemblyLoadedDic[name];
           

}
           

else
           

if(assemblyPathsDic.ContainsKey(name))
           

string path = assemblyPathsDic[name].AssemblyPath;
           

Assembly loadedAssembly = Assembly.LoadFile(path);
           

assemblyLoadedDic[name] = loadedAssembly;
           

return loadedAssembly;
           

}
           

}
           

return null;
           

}
           

根据一个目录，读取目录及子目录下所有dll

private Dictonary<string,AssemblyItem> GetAssemblyPaths(string folderPath)
{
           

string folder = folderPath;
if(!Path.IsPathRooted(folderPath))
           

folder = Path.Combine(AppDomain.CurrentDomain.BaseDirectory,folder);
           

<span style="font-family: Arial, Helvetica, sans-serif;">}</span>
           

</pre><pre name="code" class="csharp">if(!Directory.Exists(forder))
           

return null;
           

}
           

</pre><pre name="code" class="csharp">var result = new Dictonary<string,AssemblyItem>();
           

</pre><pre name="code" class="csharp">string dllfiles = Direcotry.GetFiles(folder,"*.dll",SearchOption.AllDirecotries);
           

foreach(var dllfile in dllfiles)
           

string assemblyname = Path.GetFileName(dllfile);
           

assemblyname = assemblyname.Substring(0,assemblyname.Length - 4);
           

string assemblyPath = Path.GetFullPath(dllfile);
           

</pre><pre name="code" class="csharp">var assemblyItem = new AssemblyItem()
           

AssemblyName = assemblyname,
           

AssemblyPaht = assemblyPath,
           

};
           

</pre><pre name="code" class="csharp">result[assemblyname] = assemblyItem;
           

</pre><pre name="code" class="csharp">}
           

</pre><pre name="code" class="csharp">return resutl;
