我正在尝试在运行时编译代码并在其中创建其中一个类的实例,但在使用c#6+功能(如字符串插值)时会出现一些错误。这是我用来编译的代码:
using (var cs = new CSharpCodeProvider())
{
var assembly = typeof(MyType).Assembly;
var cp = new CompilerParameters()
{
GenerateInMemory = false,
GenerateExecutable = false,
IncludeDebugInformation = true,
};
if (Environment.OSVersion.Platform.ToString() != "Unix") cp.TempFiles = new TempFileCollection(Environment.GetEnvironmentVariable("TEMP"), true);
else cp.TempFiles.KeepFiles = true;
cp.ReferencedAssemblies.Add("System.dll");
cp.ReferencedAssemblies.Add("System.Core.dll");
cp.ReferencedAssemblies.Add(assembly.Location);
CompilerResults cr;
if (Directory.Exists(path))
{
string[] files = Directory.GetFiles(path, "*.cs", SearchOption.AllDirectories);
cr = cs.CompileAssemblyFromFile(cp, files);
}
else cr = cs.CompileAssemblyFromFile(cp, new string[] { path });
if (cr.Errors.HasErrors)
throw new Exception("Compliation failed, check your code.");
var types = cr.CompiledAssembly.GetTypes();
var myType = types.Where(x => x.GetInterfaces().Contains(typeof(MyType))).FirstOrDefault();
if (myType == null)
throw new TypeLoadException("Could not find MyType class");
return (MyType)cr.CompiledAssembly.CreateInstance(myType.FullName);
}
现在,如果我尝试编译使用类似代码的代码:
string name = $"My name is {name}";
我得到这个例外:
Unexpected character '$'
答案 0 :(得分:1)
该问题的解决方法是使用Microsoft.CodeDom.Providers.DotNetCompilerPlatform。我还必须将using Microsoft.CSharp
更改为Microsoft.CodeDom.Providers.DotNetCompilerPlatform

非常感谢帮助我解决这个问题的@mjwillis。
