如何释放 Assembly 调用的dll文件
Form loadfm()
{
String pjname="pjh.dll";
Assembly assm = Assembly.LoadFrom(pjname);
Type TypeToLoad= assm.GetType("htcn.piaoju.money");
object obj;
obj = Activator.CreateInstance(TypeToLoad);
Form fm = null;

fm = (Form)obj;
return fm;
}

如果释放Assembly?

最好新建一个AppDomain，然后在那个AppDomain里加载Assembly。用完以后释放AppDomain。貌似Assembly不能单独释放，只能通过释放AppDomain来实现。

[hanjun1024]

            //创建AppDomain
            AppDomain dom = AppDomain.CreateDomain("execDom");
            //加载Assembly
            dom.ExecuteAssembly(path);
            //使用后释放AppDomain
            AppDomain.Unload(dom);

有没有实例

[changjiangzhibin]

次序好似:LoadFrom-->CreateInstance-->GetType

问题解决：

AppDomainSetup ads = new AppDomainSetup();
ads.ShadowCopyFiles = "true";
AppDomain.CurrentDomain.SetShadowCopyFiles();
Evidence adevidence = AppDomain.CurrentDomain.Evidence;
AppDomain newDomain = AppDomain.CreateDomain("newDomain", adevidence, ads);
newDomain.SetShadowCopyFiles();

byte[] rawAssembly = loadFile(pjname);
Assembly assm = newDomain.Load(rawAssembly, null);
object obj = assm.CreateInstance("htcn.piaoju.money");
Form fm = null;
fm = (Form)obj;
return fm;

[musclecn]

private byte[] loadFile(string filename)
{
FileStream fs = new FileStream(filename, FileMode.Open);
byte[] buffer = new byte[(int)fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
fs = null;
return buffer;

}
