命名空间:
System.Net.Http.Headers
程序集:
System.Net.Http.dll, netstandard.dll

RFC 2616 中定义标头及其值的集合。A collection of headers and their values as defined in RFC 2616.

public ref class HttpHeaders abstract : System::Collections::Generic::IEnumerable<System::Collections::Generic::KeyValuePair<System::String ^, System::Collections::Generic::IEnumerable<System::String ^> ^>>
public abstract class HttpHeaders : System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<string,System.Collections.Generic.IEnumerable<string>>>
type HttpHeaders = class
    interface seq<KeyValuePair<string, seq<string>>>
    interface IEnumerable
Public MustInherit Class HttpHeaders
Implements IEnumerable(Of KeyValuePair(Of String, IEnumerable(Of String)))

构造函数

HttpHeaders()

初始化 HttpHeaders 类的新实例。Initializes a new instance of the HttpHeaders class.

方法

Add(String, IEnumerable<String>)

添加指定的标头及其值到 HttpHeaders 集合中。Adds the specified header and its values into the HttpHeaders collection.
Add(String, String)

添加指定的标头及其值到 HttpHeaders 集合中。Adds the specified header and its value into the HttpHeaders collection.
Clear()

从 HttpHeaders 集合中移除所有标头。Removes all headers from the HttpHeaders collection.
Contains(String)

在 HttpHeaders 集合中存在特定标头时返回。Returns if a specific header exists in the HttpHeaders collection.
Equals(Object)

确定指定的对象是否等于当前对象。Determines whether the specified object is equal to the current object.

(继承自 Object)
GetEnumerator()

返回可循环访问 HttpHeaders 实例的枚举器。Returns an enumerator that can iterate through the HttpHeaders instance.
GetHashCode()

用作默认哈希函数。Serves as the default hash function.

(继承自 Object)
GetType()

获取当前实例的 Type。Gets the Type of the current instance.

(继承自 Object)
GetValues(String)

返回存储于 HttpHeaders 集合中的指定标头的所有标头值。Returns all header values for a specified header stored in the HttpHeaders collection.
MemberwiseClone()

创建当前 Object 的浅表副本。Creates a shallow copy of the current Object.

(继承自 Object)
Remove(String)

从 HttpHeaders 集合中移除指定的标头。Removes the specified header from the HttpHeaders collection.
ToString()

返回表示当前 HttpHeaders 对象的字符串。Returns a string that represents the current HttpHeaders object.
TryAddWithoutValidation(String, IEnumerable<String>)

返回一个值，该值指示指定的标头及其值是否添加到 HttpHeaders 集合，而无需验证提供的信息。Returns a value that indicates whether the specified header and its values were added to the HttpHeaders collection without validating the provided information.
TryAddWithoutValidation(String, String)

返回一个值，该值指示指定的标头及其值是否添加到了 HttpHeaders 集合，而无需验证提供的信息。Returns a value that indicates whether the specified header and its value were added to the HttpHeaders collection without validating the provided information.
TryGetValues(String, IEnumerable<String>)

如果指定的标头和指定的值存储在 HttpHeaders 集合中，则返回。Return if a specified header and specified values are stored in the HttpHeaders collection.

显式界面实现

IEnumerable.GetEnumerator()

获取可循环访问 HttpHeaders 的枚举器。Gets an enumerator that can iterate through a HttpHeaders.

扩展方法

CopyToDataTable<T>(IEnumerable<T>)

CopyToDataTable<T>(IEnumerable<T>, DataTable, LoadOption, FillErrorEventHandler)

在给定其泛型参数 T 为 DataRow 的输入 DataTable 对象的情况下，将 IEnumerable<T> 对象复制到指定的 DataRow。Copies DataRow objects to the specified DataTable, given an input IEnumerable<T> object where the generic parameter T is DataRow.
Cast<TResult>(IEnumerable)

将 IEnumerable 的元素强制转换为指定的类型。Casts the elements of an IEnumerable to the specified type.
OfType<TResult>(IEnumerable)

根据指定类型筛选 IEnumerable 的元素。Filters the elements of an IEnumerable based on a specified type.
AsParallel(IEnumerable)

启用查询的并行化。Enables parallelization of a query.
AsQueryable(IEnumerable)
