注解

XmlDsigBase64Transform需要对与元素的编码内容关联的原始数据进行签名时，请使用 对象。

描述 XmlDsigBase64Transform 对象的统一资源标识符 (URI) 由 XmlDsigBase64TransformUrl 字段定义。

有关解码转换的详细信息 Base64 ，请参阅 W3C XMLDSIG 规范的第 6.6.2 节。

构造函数

XmlDsigBase64Transform()

初始化 XmlDsigBase64Transform 类的新实例。

属性

Algorithm

获取或设置用于标识当前转换所执行的算法的统一资源标识符 (URI)。

(继承自 Transform)
Context

获取或设置一个 XmlElement 对象，该对象表示当前 Transform 对象运行的文档上下文。

(继承自 Transform)
InputTypes

获取一个类型数组，这些类型是当前 XmlDsigBase64Transform 对象的 LoadInput(Object) 方法的有效输入。
OutputTypes

获取一个类型数组，这些类型是当前 XmlDsigBase64Transform 对象的 GetOutput() 方法的可能输出。
PropagatedNamespaces

获取或设置一个 Hashtable 对象，该对象包含传播到签名中的命名空间。

(继承自 Transform)
Resolver

设置当前的 XmlResolver 对象。

(继承自 Transform)

方法

Equals(Object)

确定指定对象是否等于当前对象。

(继承自 Object)
GetDigestedOutput(HashAlgorithm)

当在派生类中重写时，返回与 Transform 对象关联的摘要。

(继承自 Transform)
GetHashCode()

作为默认哈希函数。

(继承自 Object)
GetInnerXml()

返回 XmlDsigBase64Transform 对象的参数的 XML 表示形式，适合以 XMLDSIG <Transform> 元素的子元素的形式来包含这些参数。
GetOutput()

返回当前 XmlDsigBase64Transform 对象的输出。
GetOutput(Type)

返回 Stream 类型的当前 XmlDsigBase64Transform 对象的输出。
GetType()

获取当前实例的 Type。

(继承自 Object)
GetXml()

返回当前 Transform 对象的 XML 表示形式。

(继承自 Transform)
LoadInnerXml(XmlNodeList)

将指定的 XmlNodeList 对象分析为 <Transform> 元素的特定于转换的内容；此方法不受支持，因为 XmlDsigBase64Transform 对象没有内部 XML 元素。
LoadInput(Object)

将指定的输入加载到当前 XmlDsigBase64Transform 对象中。
MemberwiseClone()

创建当前 Object 的浅表副本。

(继承自 Object)
ToString()

返回表示当前对象的字符串。

(继承自 Object)
