how to change these windows form code to web form code?

hi, 


i'm a beginner of c#,i want to know how to change these windows form code to web form code





////////////


private void buttonSign_Click(


			object sender, System.EventArgs e)


		{


			//get original message as byte array


			byte[] messagebytes = Encoding.UTF8.GetBytes(


				textOriginalMessage.Text);


			//create digest of original message using SHA1


			SHA1 sha1  = new SHA1CryptoServiceProvider();


			byte[] hashbytes = 


				sha1.ComputeHash(messagebytes);


			//display hash bytes in hex format


			StringBuilder sb = new StringBuilder();


			for (int i=0; i<hashbytes.Length; i++)


			{


				sb.Append(String.Format(


					"{0,2:X2} ", hashbytes[i]));


			}


			textMessageDigestSHA1.Text = sb.ToString();


			//create DSA object using default key


			DSACryptoServiceProvider dsa = 


				new DSACryptoServiceProvider();


			//sign hash using OID for SHA-1


			signaturebytes =


				dsa.SignHash(hashbytes, "1.3.14.3.2.26");


			//provide DSA parameters to verification


			dsaparams = dsa.ExportParameters(false);


			buttonVerify.Text=dsaparams.ToString();


			//display digital signature in hex format


			sb = new StringBuilder();


			for (int i=0; i<signaturebytes.Length; i++)


			{


				sb.Append(String.Format(


					"{0,2:X2} ", signaturebytes[i]));


			}


			textSignature.Text = sb.ToString();


			//display DSA parameter details in hex format


			sb = new StringBuilder();


			for (int i=0; i<dsaparams.P.Length; i++)


			{


				sb.Append(String.Format(

			buttonVerify.Select();


		}


		private void buttonVerify_Click(


			object sender, System.EventArgs e)


		{


			//get possibly modified message as byte array

			//create digest of original message using SHA1


			SHA1 sha1  = new SHA1CryptoServiceProvider();


			byte[] hashbytes =

			dsa.ImportParameters(dsaparams);


			//do verification on hash using OID for SHA-1


			bool match = dsa.VerifyHash(


				hashbytes, "1.3.14.3.2.26", signaturebytes);


			//show message box with result of verification


			String strResult;


			if (match)


				strResult = "VerifySignature returned TRUE";


			else


				strResult = "VerifySignature returned FALSE";


			MessageBox.Show(

				"Result From Calling VerifySignature",


				MessageBoxButtons.OK,


				MessageBoxIcon.Exclamation);

			buttonVerify.Enabled = false;


			buttonVerify.Select();


		}


		//variables communicated from signing to verifying


		DSAParameters dsaparams;


		byte[] signaturebytes;

are you getting errors? because the listed code (I skimmed so I might have missed something) doesn't have any winform specific calls.. exception is the MessageBox.. but you can replace that with just a simple label and change the text of that.. or a slew of other methods..
ah! pooh!

Can u rewrite this code for me with web form c# asp.net?

sorry.. this is a help forum.. not do your homework/work forum..
ah! pooh!
