Properties

Capacity

public int Capacity { get; }

Property Value

int

Count

Gets the number of elements contained in the ICollection<T>.

public int Count { get; }

Property Value

int

The number of elements contained in the ICollection<T>.

IsReadOnly

Gets a value indicating whether the ICollection<T> is read-only.

public bool IsReadOnly { get; }

Property Value

bool

true if the ICollection<T> is read-only; otherwise, false.

this[int]

Gets or sets the element at the specified index.

public NpgsqlPoint this[int index] { get; set; }

Parameters

index int

The zero-based index of the element to get or set.

Property Value

NpgsqlPoint

The element at the specified index.

Exceptions

ArgumentOutOfRangeException

index is not a valid index in the IList<T>.

NotSupportedException

The property is set and the IList<T> is read-only.

Methods

Add(NpgsqlPoint)

Adds an item to the ICollection<T>.

public void Add(NpgsqlPoint item)

Parameters

item NpgsqlPoint

The object to add to the ICollection<T>.

Exceptions

NotSupportedException

The ICollection<T> is read-only.

Clear()

Removes all items from the ICollection<T>.

public void Clear()

Exceptions

NotSupportedException

The ICollection<T> is read-only.

Contains(NpgsqlPoint)

Determines whether the ICollection<T> contains a specific value.

public bool Contains(NpgsqlPoint item)

Parameters

item NpgsqlPoint

The object to locate in the ICollection<T>.

Returns

bool

true if item is found in the ICollection<T>; otherwise, false.

CopyTo(NpgsqlPoint[], int)

Copies the elements of the ICollection<T> to an Array, starting at a particular Array index.

public void CopyTo(NpgsqlPoint[] array, int arrayIndex)

Parameters

array NpgsqlPoint[]

The one-dimensional Array that is the destination of the elements copied from ICollection<T>. The Array must have zero-based indexing.

arrayIndex int

The zero-based index in array at which copying begins.

Exceptions

ArgumentNullException

array is null.

ArgumentOutOfRangeException

arrayIndex is less than 0.

ArgumentException

The number of elements in the source ICollection<T> is greater than the available space from arrayIndex to the end of the destination array.

Equals(NpgsqlPolygon)

Indicates whether the current object is equal to another object of the same type.

public bool Equals(NpgsqlPolygon other)

Parameters

other NpgsqlPolygon

An object to compare with this object.

Returns

bool

true if the current object is equal to the other parameter; otherwise, false.

Equals(object?)

Indicates whether this instance and a specified object are equal.

public override bool Equals(object? obj)

Parameters

obj object

The object to compare with the current instance.

Returns

bool

true if obj and this instance are the same type and represent the same value; otherwise, false.

GetEnumerator()

Returns an enumerator that iterates through the collection.

public IEnumerator<NpgsqlPoint> GetEnumerator()

Returns

IEnumerator<NpgsqlPoint>

An enumerator that can be used to iterate through the collection.

GetHashCode()

Returns the hash code for this instance.

public override int GetHashCode()

Returns

int

A 32-bit signed integer that is the hash code for this instance.

IndexOf(NpgsqlPoint)

Determines the index of a specific item in the IList<T>.

public int IndexOf(NpgsqlPoint item)

Parameters

item NpgsqlPoint

The object to locate in the IList<T>.

Returns

int

The index of item if found in the list; otherwise, -1.
