AsymmetricAlgorithm.SignatureAlgorithm 属性
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
当在派生类中实现时，请获取签名算法的名称。 否则，将始终引发 NotImplementedException。

下面的代码示例演示如何重写 SignatureAlgorithm 属性以返回签名算法的名称。 此代码示例是为 AsymmetricAlgorithm 类提供的一个更大示例的一部分。
// This example uses the SHA1 algorithm.
// Due to collision problems with SHA1, Microsoft recommends SHA256 or better.
public:
property String^ SignatureAlgorithm
{
virtual String^ get() override
{
return "http://www.w3.org/2000/09/xmldsig#rsa-sha1";
}
}
C#
// This example uses the SHA1 algorithm.
// Due to collision problems with SHA1, Microsoft recommends SHA256 or better.
public override string SignatureAlgorithm
{

}
