如何在C#中使用Windows个人用户证书对任意字符串进行签名

string certificateFilePath = "path/to/certificate.pfx";
string certificatePassword = "password";

X509Certificate2 certificate = new X509Certificate2(certificateFilePath, certificatePassword);

string dataToSign = "要签名的字符串";

byte[] dataBytes = Encoding.UTF8.GetBytes(dataToSign);
using (RSACryptoServiceProvider rsa = (RSACryptoServiceProvider)certificate.PrivateKey)
{
    byte[] signatureBytes = rsa.SignData(dataBytes, new SHA256CryptoServiceProvider());
    string signature = Convert.ToBase64String(signatureBytes);
}
