想了解C#动态编译并执行字符串样例的相关内容吗,王宝会在本文为您仔细讲解C#动态编译并执行字符串的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:C#,动态编译,字符串,下面大家一起来学习吧。
using System;
using Microsoft.CSharp;
using System.CodeDom.Compiler;
class Program
{
public static void Main()
{
// The C# code to execute
string code = "using System; " +
"using System.IO; " +
"public class MyClass{ " +
" public static void PrintConsole(string message){ " +
" Console.WriteLine(message); " +
" } " +
"} ";
// Compiler and CompilerParameters
CSharpCodeProvider codeProvider = new CSharpCodeProvider();
CompilerParameters compParameters = new CompilerParameters();
// Compile the code
CompilerResults res = codeProvider.CompileAssemblyFromSource(compParameters, code);
// Create a new instance of the class 'MyClass' // 有命名空间的,需要命名空间.类名
object myClass = res.CompiledAssembly.CreateInstance("MyClass");
// Call the method 'PrintConsole' with the parameter 'Hello World'
// "Hello World" will be written in console
myClass.GetType().GetMethod("PrintConsole").Invoke(myClass, new object[] {"Hello World" });
Console.Read();
}
