Tuple<T1,T2,T3>.IStructuralEquatable.GetHashCode(IEqualityComparer) 方法
定义
使用指定的计算方法计算当前 Tuple<T1,T2,T3> 对象的哈希代码。Calculates the hash code for the current Tuple<T1,T2,T3> object by using a specified computation method.
virtual int System.Collections.IStructuralEquatable.GetHashCode(System::Collections::IEqualityComparer ^ comparer) = System::Collections::IStructuralEquatable::GetHashCode;
int IStructuralEquatable.GetHashCode (System.Collections.IEqualityComparer comparer);
abstract member System.Collections.IStructuralEquatable.GetHashCode : System.Collections.IEqualityComparer -> int
override this.System.Collections.IStructuralEquatable.GetHashCode : System.Collections.IEqualityComparer -> int
Function GetHashCode (comparer As IEqualityComparer) As Integer Implements IStructuralEquatable.GetHashCode
参数
- comparer
- IEqualityComparer
一个对象,其 GetHashCode(Object) 方法计算当前 Tuple<T1,T2,T3> 对象的哈希代码。An object whose GetHashCode(Object) method calculates the hash code of the current Tuple<T1,T2,T3> object.
返回
32 位有符号整数哈希代码。A 32-bit signed integer hash code.
实现
注解
此成员是显式接口成员的实现。This member is an explicit interface member implementation. 它只能在 Tuple<T1,T2,T3> 实例被强制转换为 IStructuralEquatable 接口时使用。It can be used only when the Tuple<T1,T2,T3> instance is cast to an IStructuralEquatable interface.
方法只是包装对 comparer 对象实现的调用 IEqualityComparer.GetHashCode 。The method simply wraps a call to the comparer object's IEqualityComparer.GetHashCode implementation.
用于计算哈希代码的算法应为被视为相等的两个对象返回相同的哈希代码 Tuple<T1,T2,T3> 。The algorithm used to compute the hash code should return the same hash code for two Tuple<T1,T2,T3> objects that are considered to be equal.
