ProviderCollection 类

定义

表示从 ProviderBase 继承的提供程序对象的集合。Represents a collection of provider objects that inherit from ProviderBase.

public ref class ProviderCollection : System::Collections::ICollection
public class ProviderCollection : System.Collections.ICollection
type ProviderCollection = class
    interface ICollection
    interface IEnumerable
Public Class ProviderCollection
Implements ICollection

实现

注解

ProviderCollection 类利用基础 Hashtable 对象来存储提供程序名称/值对。The ProviderCollection class utilizes an underlying Hashtable object to store the provider name/value pairs.

构造函数

ProviderCollection()

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

属性

Count

获取集合中提供程序的数目。Gets the number of providers in the collection.

IsSynchronized

获取一个值,该值指示对集合的访问是否为同步的(线程安全)。Gets a value indicating whether access to the collection is synchronized (thread safe).

Item[String]

获取具有指定名称的提供程序。Gets the provider with the specified name.

SyncRoot

获取当前对象。Gets the current object.

方法

Add(ProviderBase)

将提供程序添加到集合。Adds a provider to the collection.

Clear()

从集合中移除所有项。Removes all items from the collection.

CopyTo(ProviderBase[], Int32)

从指定索引处开始,将集合中的内容复制到给定数组。Copies the contents of the collection to the given array starting at the specified index.

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()

返回一个对象,该对象实现 IEnumerator 接口以循环访问集合。Returns an object that implements the IEnumerator interface to iterate through the collection.

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 TypeGets the Type of the current instance.

(继承自 Object)
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)

从集合中删除提供程序。Removes a provider from the collection.

SetReadOnly()

将集合设置为只读。Sets the collection to be read-only.

ToString()

返回一个表示当前对象的 string。Returns a string that represents the current object.

(继承自 Object)

显式接口实现

ICollection.CopyTo(Array, Int32)

ProviderCollection 的元素复制到一个数组中从特定的数组索引开始的位置。Copies the elements of the ProviderCollection to an array, starting at a particular array index.

扩展方法

Cast<TResult>(IEnumerable)

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)

IEnumerable 转换为 IQueryableConverts an IEnumerable to an IQueryable.
