protected TElX509Certificate TELX509 = new TElX509Certificate();
protected void Button1_Click(object sender, EventArgs e)
string pwd="1234";
FileStream FS = File.OpenRead("C:\\abcd.pvk");
TELX509.LoadKeyFromStreamPVK(FS, pwd, 0);

FileStream FS2 = File.OpenRead("C:\\abcd.cer");

FileStream sFS = File.OpenWrite("C:\\test.pfx");
TELX509.SaveToStreamPFX(sFS, "1234");

The abcd.pvk password is "1234",When I not for the LoadKeyFromStreamPVK password, produces test.pfx does not have the private key; But after establishment password, run-time error.
Why don't I know?

You have to load a certificate prior to loading private key material. As you are trying to load the key into empty certificate object, there's no associated public key material and thus the exception is thrown.
