根据这篇出色的博客文章,我编写了一个帮助类来实现它。
用法:
webBrowser.Document.InvokeScript("TestMethod", new object[] {
new Reflector(new { helloProperty = "Hello!", byeProperty = "Bye!" }) });
代码:
[ComVisible(true), ClassInterface(ClassInterfaceType.None)]
public class Reflector :
System.Reflection.IReflect
{
object _target;
protected Reflector() { }
public Reflector(object target)
{
Debug.Assert(target != null);
_target = target;
}
public object Target
{
get { return _target; }
}
#region IReflect
public FieldInfo GetField(string name, BindingFlags bindingAttr)
{
return this._target.GetType().GetField(name, bindingAttr);
}
public FieldInfo[] GetFields(BindingFlags bindingAttr)
{
return this._target.GetType().GetFields(bindingAttr);
}
public MemberInfo[] GetMember(string name, BindingFlags bindingAttr)
{
return this._target.GetType().GetMember(name, bindingAttr);
}
public MemberInfo[] GetMembers(BindingFlags bindingAttr)

{

{

{

return this._target;
else if (invokeAttr.HasFlag(BindingFlags.GetProperty) && args.Length == 0)
return this._target.ToString();
