CompilerParameters.ReferencedAssemblies -- Add reference to System.Web.UI.WebControls
提问by cllpse
I am compiling classes at run-time using the CodeDomProviderclass. This works fine for classes only using the Systemnamespace:
我正在使用类在运行时编译CodeDomProvider类。这适用于仅使用System命名空间的类：
using System;
public class Test
{
public String HelloWorld()
{
return "Hello World!";
}
}
If I try to compile a class using System.Web.UI.WebControlsthough, I get this error:
如果我尝试使用System.Web.UI.WebControls虽然编译一个类，我会收到此错误：
{error CS0006: Metadata file 'System.Web.UI.WebControls' could not be found} System.CodeDom.Compiler.CompilerError
{错误 CS0006：找不到元数据文件“System.Web.UI.WebControls”} System.CodeDom.Compiler.CompilerError
Here's a snippet of my code:
这是我的代码片段：
var cp = new CompilerParameters();
cp.ReferencedAssemblies.Add("System.Web.UI.WebControls");
How do I reference the System.Web.UI.WebControlsnamespace?
如何引用System.Web.UI.WebControls命名空间？

You reference assemblies, not namespaces. You should use MSDN to look up the name of the assembly that contains the classes you need to use: in this case it's going to be:
您引用程序集，而不是命名空间。您应该使用 MSDN 查找包含您需要使用的类的程序集的名称：在这种情况下，它将是：
var cp = new CompilerParameters();
cp.ReferencedAssemblies.Add("System.Web.dll");

You can loop through all the currently loaded assemblies:
您可以遍历所有当前加载的程序集：
var assemblies = AppDomain.CurrentDomain
.GetAssemblies()
.Where(a => !a.IsDynamic)
.Select(a => a.Location);
cp.ReferencedAssemblies.AddRange(assemblies.ToArray());

This proved to be a little less brute force in my case. I was building an addin and there were 730 assemblies loaded in the current domain so there was major lag involved.
在我的情况下，这被证明不是蛮力。我正在构建一个插件，当前域中加载了 730 个程序集，因此存在重大延迟。
var assemblies = someType.Assembly.GetReferencedAssemblies().ToList();
var assemblyLocations =
assemblies.Select(a =>
Assembly.ReflectionOnlyLoad(a.FullName).Location).ToList();
assemblyLocations.Add(someType.Assembly.Location);
cp.ReferencedAssemblies.AddRange(assemblyLocations.ToArray());
