static member Create : string -> System.Security.Cryptography.ECDsa

Public Shared Function Create (algorithm As String) As ECDsa

参数

algorithm: String

ECDSA 实现的名称。以下字符串都引用相同的实现，这是.NET框架中当前唯一支持的实现：

“ECDsa”
“ECDsaCng”
“System.Security.Cryptography.ECDsaCng”

还可以提供自定义 ECDSA 实现的名称。

ECDsa

此类的指定实现的新实例。如果指定的算法名称不映射到 ECDSA 实现，此方法将 null返回。

属性: RequiresUnreferencedCodeAttribute ObsoleteAttribute

例外

ArgumentNullException

参数 algorithm 为 null.

注解

如果开发对象自己的实现 ECDsa ，则可以使用 Create(String) 方法重载创建自定义 algorithm 字符串来指定实现。

如果为 algorithm 参数指定自定义值，该 CryptoConfig 对象将使用它来确定是否可以创建 ECDSA 对象。
