c# - 如何在动态创建的dll上设置版本

Question

我需要一些帮助来设置动态创建的 dll 的版本。

我正在使用 CodeDomProvider 创建 dll，但无法设置输出程序集的版本。

我在一些博客中看到，只有设置编译器参数来生成可执行文件而不是在内存中才能完成此操作。

我的代码是:

using System;
using System.CodeDom.Compiler;
using System.Diagnostics;
using System.Linq;

namespace dynamicDll
{
    class Program
    {
        static void Main(string[] args)
        {
            CompilerParameters parameters = new CompilerParameters();
            parameters.GenerateInMemory = true;
            parameters.GenerateExecutable = false;
            parameters.IncludeDebugInformation = true;
            parameters.OutputAssembly = "Dynamic.dll";
            var assemblies = AppDomain.CurrentDomain.GetAssemblies()
                            .Where(a => !a.IsDynamic)
                            .Select(a => a.Location);
            parameters.ReferencedAssemblies.AddRange(assemblies.ToArray());

            CompilerResults cr = CodeDomProvider.CreateProvider("CSharp")
                .CompileAssemblyFromSource(parameters, @"          
namespace Dynamic
                    {
                        public class DynamicDllClass
                        {
                            public int X { get {return 7;}}
                        }
                    }");
            cr.CompiledAssembly.GetName().Version = new Version("1.0.0.0");
            var instance = cr.CompiledAssembly.CreateInstance("Dynamic.DynamicDllClass");
            int x = (int) instance.GetType().GetProperty("X").GetGetMethod().Invoke(instance, null);
            Debug.Assert(x==7);
            Debug.Assert(cr.CompiledAssembly.FullName.Contains("1.0.0.0"));
        }
    }
}

谢谢linuser !

以下代码运行良好!

using System;
using System.CodeDom.Compiler;
using System.Diagnostics;
using System.Linq;
using System.Reflection;

namespace dynamicDll
{
    class Programs
    {
        static void Mains(string[] args)
        {
            CompilerParameters parameters = new CompilerParameters();
            parameters.GenerateInMemory = true;
            parameters.GenerateExecutable = false;
            parameters.IncludeDebugInformation = true;
            parameters.OutputAssembly = "Dynamic.dll";
            var assemblies = AppDomain.CurrentDomain.GetAssemblies()
                            .Where(a => !a.IsDynamic)
                            .Select(a => a.Location);
            parameters.ReferencedAssemblies.AddRange(assemblies.ToArray());
            var versionString = "1.0.0.0";

            CompilerResults cr = CodeDomProvider.CreateProvider("CSharp")
                .CompileAssemblyFromSource(parameters, @"
using System.Reflection;
[assembly: AssemblyVersion(" + "\"" + versionString + "\"" + @")]                    
namespace Dynamic
                    {
                        public class DynamicDllClass
                        {
                            public int X { get {return 7;}}
                        }
                    }");

            var instance = cr.CompiledAssembly.CreateInstance("Dynamic.DynamicDllClass");
            int x = (int) instance.GetType().GetProperty("X").GetGetMethod().Invoke(instance, null);
            Debug.Assert(x==7);
            Debug.Assert(cr.CompiledAssembly.FullName.Contains(versionString));
        }
    }
}
