AsymmetricAlgorithm.SignatureAlgorithm 属性

定义

命名空间:

System.Security.Cryptography

程序集:

System.Security.Cryptography.Primitives.dll

程序集:

System.Security.Cryptography.dll

程序集:

mscorlib.dll

程序集:

netstandard.dll

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。

public:
 virtual property System::String ^ SignatureAlgorithm { System::String ^ get(); };

public:
 abstract property System::String ^ SignatureAlgorithm { System::String ^ get(); };

public virtual string? SignatureAlgorithm { get; }

public virtual string SignatureAlgorithm { get; }

public abstract string SignatureAlgorithm { get; }

member this.SignatureAlgorithm : string

Public Overridable ReadOnly Property SignatureAlgorithm As String

Public MustOverride ReadOnly Property SignatureAlgorithm As String

属性值

String

签名算法的名称。

示例

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。 此代码示例是为类提供的大型示例的 AsymmetricAlgorithm 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";
        }
    }

// This example uses the SHA1 algorithm.
// Due to collision problems with SHA1, Microsoft recommends SHA256 or better.
public override string SignatureAlgorithm 
{
    get {return "http://www.w3.org/2000/09/xmldsig#rsa-sha1";}
}

' This example uses the SHA1 algorithm.
' Due to collision problems with SHA1, Microsoft recommends SHA256 or better.
Public Overrides ReadOnly Property SignatureAlgorithm() As String
    Get
        Return "http://www.w3.org/2000/09/xmldsig#rsa-sha1"
    End Get
End Property
