c# 如何把字符串转化为代码!

Answer 1

你是说你自己写的C#代码字符串 然后在程序中运行吗?看看这个吧using System; using System.Reflection; using System.Globalization; using Microsoft.CSharp;using System.CodeDom; using System.CodeDom.Compiler;using System.Text; namespace ConsoleApplication1 { public class Program { static void Main(string[] args) { // 1.CSharpCodePrivoder CSharpCodeProvider objCSharpCodePrivoder = new CSharpCodeProvider(); // 2.ICodeComplier ICodeCompiler objICodeCompiler = objCSharpCodePrivoder.CreateCompiler(); // 3.CompilerParameters CompilerParameters objCompilerParameters = new CompilerParameters(); objCompilerParameters.ReferencedAssemblies.Add("System.dll"); objCompilerParameters.GenerateExecutable = false; objCompilerParameters.GenerateInMemory = true; // 4.CompilerResults CompilerResults cr = objICodeCompiler.CompileAssemblyFromSource(objCompilerParameters, GenerateCode()); if (cr.Errors.HasErrors) { Console.WriteLine("编译错误："); foreach (CompilerError err in cr.Errors) { Console.WriteLine(err.ErrorText); } } else { // 通过反射，调用HelloWorld的实例 Assembly objAssembly = cr.CompiledAssembly; object objHelloWorld = objAssembly.CreateInstance("DynamicCodeGenerate.HelloWorld"); MethodInfo objMI = objHelloWorld.GetType().GetMethod("OutPut"); Console.WriteLine(objMI.Invoke(objHelloWorld, null)); } Console.ReadLine(); } static string GenerateCode() { StringBuilder sb = new StringBuilder(); sb.Append("using System;"); sb.Append(Environment.NewLine); sb.Append("namespace DynamicCodeGenerate"); sb.Append(Environment.NewLine); sb.Append("{"); sb.Append(Environment.NewLine); sb.Append(" public class HelloWorld"); sb.Append(Environment.NewLine); sb.Append(" {"); sb.Append(Environment.NewLine); sb.Append(" public string OutPut()"); sb.Append(Environment.NewLine); sb.Append(" {"); sb.Append(Environment.NewLine); sb.Append(" return \"Hello world!\";"); sb.Append(Environment.NewLine); sb.Append(" }"); sb.Append(Environment.NewLine); sb.Append(" }"); sb.Append(Environment.NewLine); sb.Append("}"); string code = sb.ToString(); Console.WriteLine(code); Console.WriteLine(); return code; } }} 我来完善答案完善答案通过审核后，可获得3点财富值最新回答：2012-02-05 20:53 版本：1个历史版本
