ValueTuple is a structure introduced in C# 7.0 which represents the value type Tuple. It allows you to store a data set which contains multiple values that may or may not be related to each other. Item1 Property is used to get the first unnamed element of the given value tuple. It is applicable on every value tuple like 1-ValueTuple, 2-ValueTuple, and so on.
public T1 Item1;
Here, T1 is the field value of a ValueTuple<> structure. This ValueTuple<> can be 1-ValueTuple, or 2-ValueTuple, or 3-ValueTuple, or 4-ValueTuple, or 5-ValueTuple, or 6-ValueTuple, or 7-ValueTuple, or 8-ValueTuple.
Example: In the below code, you can see that we are accessing the first element of each value tuple.
