具体的实现可参考下面的代码。如需要生成程序集文件,可参考《使用CodeDom生成程序集》。
using System;
using System.Reflection;
using System.Globalization;
using Microsoft.CSharp;
using System.CodeDom;
using System.CodeDom.Compiler;
namespace ConsoleApplication1
{
public class Program
{
static void Main(string[] args)
{
// 定义需要动态执行的 C# 代码字符串,当然也可从文本文件中读取。
string code = @"
using System;
namespace MyNamespace
{
public class MyClass
{
private string name;
public MyClass(string name)
{
this.name = name;
}
public void Test()
{
Console.WriteLine(""{0} - {1}"", name, DateTime.Now);
}
}
}
";
// 创建编译器对象
CSharpCodeProvider p = new CSharpCodeProvider();
ICodeCompiler cc = p.CreateCompiler();
// 设置编译参数
CompilerParameters options = new CompilerParameters();
options.ReferencedAssemblies.Add("System.dll");
options.GenerateInMemory = true;
options.OutputAssembly = "MyTest";
// 开始编译
CodeSnippetCompileUnit cu = new CodeSnippetCompileUnit(code);
CompilerResults cr = cc.CompileAssemblyFromDom(options, cu);
// 执行动态程序集相关内容。
Type t = cr.CompiledAssembly.GetType("MyNamespace.MyClass");
object o = cr.CompiledAssembly.CreateInstance("MyNamespace.MyClass", false, BindingFlags.Default,
null, new object[] { "Tom" }, CultureInfo.CurrentCulture, null);
t.InvokeMember("Test", BindingFlags.Instance | BindingFlags.Public | BindingFlags.InvokeMethod,
null, o, null);
}
}
}
