Tuple<'T1, 'T2> Class
Represents a 2-tuple, or pair.
Assembly: mscorlib (in mscorlib.dll)
Returns a value that indicates whether the current Object.Equals(Object).)object is equal to a specified object.(Overrides
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
Returns the hash code for the current Object.GetHashCode().)object.(Overrides
Returns a string that represents the value of this Object.ToString().)instance.(Overrides
Compares the currentobject to a specified object by using a specified comparer, and returns an integer that indicates whether the current object is before, after, or in the same position as the specified object in the sort order.
Returns a value that indicates whether the currentobject is equal to a specified object based on a specified comparison method.
Calculates the hash code for the currentobject by using a specified computation method.
Compares the currentobject to a specified object and returns an integer that indicates whether the current object is before, after, or in the same position as the specified object in the sort order.
A tuple is a data structure that has a specific number and sequence of values. The KeyValuePair<'TKey, 'TValue> structure.class represents a 2-tuple, or pair, which is a tuple that has two components. A 2-tuple is similar to a
You can instantiate a Tuple<'T1, 'T2> constructor or the static Tuple.Create<'T1, 'T2>('T1, 'T2) method. You can retrieve the values of the tuple's components by using the read-only Item1 and Item2 instance properties.object by calling either the
Tuples are commonly used in four different ways:
To represent a single set of data. For example, a tuple can represent a record in a database, and its components can represent that record's fields.
To provide easy access to, and manipulation of, a data set. The following example defines an array ofobjects that contain the names of students and their corresponding test scores. It then iterates the array to calculate the mean test score.
To return multiple values from a method without the use of out parameters (in C#) or ByRef parameters (in Visual Basic). For example, the following example uses aobject to return the quotient and the remainder that result from integer division.
To pass multiple values to a method through a single parameter. For example, the Thread.Start(Object) method has a single parameter that lets you supply one value to the method that the thread executes at startup. If you supply a object as the method argument, you can supply the thread’s startup routine with two items of data.
