跟进这个出色的答案,我想知道使用dynamic
关键字的 DLR 是否可以允许以不那么冗长的方式为生成的程序集编写代码。
例如,上述答案的代码是否可以:
using (Microsoft.CSharp.CSharpCodeProvider foo =
new Microsoft.CSharp.CSharpCodeProvider())
{
var res = foo.CompileAssemblyFromSource(
new System.CodeDom.Compiler.CompilerParameters() {
GenerateInMemory = true
},
"public class FooClass { public string Execute() { return \"output!\";}}"
);
var type = res.CompiledAssembly.GetType("FooClass");
var obj = Activator.CreateInstance(type);
var output = type.GetMethod("Execute").Invoke(obj, new object[] { });
}
变成这样的东西:
using (Microsoft.CSharp.CSharpCodeProvider foo =
new Microsoft.CSharp.CSharpCodeProvider())
{
var res = foo.CompileAssemblyFromSource(
new System.CodeDom.Compiler.CompilerParameters() {
GenerateInMemory = true
},
"public class FooClass { public string Execute() { return \"output!\";}}"
);
var type = res.CompiledAssembly.GetType("FooClass");
dynamic obj = Activator.CreateDynamicInstance(type);
var output = obj.Execute();
}
