C＃，从后台线程调用匿名方法（Action <>）(C#, invoke anonymous method (Action<>) from background thread)

 这应该很简单！  
 我想创建一个匿名的Action <>委托来执行GUI更新，我将从其他几个匿名委托调用它（它将在不同的线程上运行）。  
    void Test() {

        Action<string> invokeDisplay = new Action<string>(delegate(string Element) {
            //Do a variety of things to my GUI depending on Element parameter
        });


        MethodInvoker opLong1 = new MethodInvoker(delegate() {

        //  Do long task

            this.Invoke(invokeDisplay("long1"));
        });

        MethodInvoker opLong2 = new MethodInvoker(delegate() {

        //  Do long task

            this.Invoke(invokeDisplay("long2"));
        });

        new Thread(new ThreadStart(opLong1)).Start();
        new Thread(new ThreadStart(opLong2)).Start();
    }
 
 那么这条线的正确语法是什么？  
            this.Invoke(invokeDisplay("long1"));

This should be simple! 
I want to create an anonymous Action<> delegate to perform a GUI update, which I will call from several other anonymous delegates (which will be run on separate threads). 
    void Test() {

        Action<string> invokeDisplay = new Action<string>(delegate(string Element) {
            //Do a variety of things to my GUI depending on Element parameter
        });


        MethodInvoker opLong1 = new MethodInvoker(delegate() {

        //  Do long task

            this.Invoke(invokeDisplay("long1"));
        });

        MethodInvoker opLong2 = new MethodInvoker(delegate() {

        //  Do long task

            this.Invoke(invokeDisplay("long2"));
        });

        new Thread(new ThreadStart(opLong1)).Start();
        new Thread(new ThreadStart(opLong2)).Start();
    }
 
So whats the correct syntax for this line? 
            this.Invoke(invokeDisplay("long1"));

 过了一段时间，我在bouncyCastle应用程序的示例中找到了它的完成方式。  
 它实际上比我在IText中找到的更简单直接（没有取出框架本身的亲切性）。  
 代码类似于：  
        AsymmetricCipherKeyPair signaturePair;
        X509Certificate signatureCert;

        IList certList = new ArrayList();
        IList crlList = new ArrayList();
        CmsProcessable msg = new CmsProcessableByteArray(Encoding.ASCII.GetBytes("I hate hello world!"));

        certList.Add(signatureCert);
        certList.Add(OrigCert);

        crlList.Add(SignCrl);

        IX509Store x509Certs = X509StoreFactory.Create(
            "Certificate/Collection",
            new X509CollectionStoreParameters(certList));
        IX509Store x509Crls = X509StoreFactory.Create(
            "CRL/Collection",
            new X509CollectionStoreParameters(crlList));

        CmsSignedDataGenerator gen = new CmsSignedDataGenerator();

        gen.AddSigner(signaturePair.Private, signatureCert, CmsSignedDataGenerator.DigestSha1);

        gen.AddCertificates(x509Certs);
        gen.AddCrls(x509Crls);

        CmsSignedData signedData = gen.Generate(msg, true);

        //saving in BER encoding
        Stream stream = new MemoryStream(signedData.GetEncoded());

After sometime, i've found how its done, in the examples inside the bouncyCastle app. 
It's actually quite simpler and straight foward than i had found in IText (, not taking out the geniality of the framework itself). 
The code is something like: 
        AsymmetricCipherKeyPair signaturePair;
        X509Certificate signatureCert;

        IList certList = new ArrayList();
        IList crlList = new ArrayList();
        CmsProcessable msg = new CmsProcessableByteArray(Encoding.ASCII.GetBytes("I hate hello world!"));

        certList.Add(signatureCert);
        certList.Add(OrigCert);

        crlList.Add(SignCrl);

        IX509Store x509Certs = X509StoreFactory.Create(
            "Certificate/Collection",
            new X509CollectionStoreParameters(certList));
        IX509Store x509Crls = X509StoreFactory.Create(
            "CRL/Collection",
            new X509CollectionStoreParameters(crlList));

        CmsSignedDataGenerator gen = new CmsSignedDataGenerator();

        gen.AddSigner(signaturePair.Private, signatureCert, CmsSignedDataGenerator.DigestSha1);

        gen.AddCertificates(x509Certs);
        gen.AddCrls(x509Crls);

        CmsSignedData signedData = gen.Generate(msg, true);

        //saving in BER encoding
        Stream stream = new MemoryStream(signedData.GetEncoded());
