public struct Blob : IEquatable<Blob>

Reference documentation and code samples for the Firestore API struct Blob.

An immutable sequence of bytes.

Implements

IEquatable Blob

Inherited Members

object.GetType()

Namespace

Assembly

Google.Cloud.Firestore.dll

Remarks

Although this is a struct, it's effectively just a wrapper around a Protobuf ByteString. default(Blob) acts as if it had been constructed with Empty.

Properties

ByteString

public ByteString ByteString { get; }

The underlying Protobuf ByteString.

Property Value
Type	Description
`ByteString`

this[int]

public byte this[int index] { get; }

Returns the byte at index index.

Parameter
Name	Description
`index`	`int` The index in the blob to return. Must be greater than or equal to 0, and less than Length.

Property Value
Type	Description
`byte`	The byte at index `index`.

Length

public int Length { get; }

The length of the blob, in bytes.

Property Value
Type	Description
`int`

Methods

CopyFrom(byte[])

public static Blob CopyFrom(byte[] bytes)

Constructs a new Blob by copying the current content of bytes.

Parameter
Name	Description
`bytes`	`byte` Byte array to copy.

Returns
Type	Description
`Blob`	A new blob containing a copy of `bytes`.

FromByteString(ByteString)

public static Blob FromByteString(ByteString byteString)

Constructs a new Blob wrapping the given ByteString.

Parameter
Name	Description
`byteString`	`ByteString` The ByteString to wrap. Must not be null.

Returns
Type	Description
`Blob`	A new blob wrapping `byteString`.

GetHashCode()

public override int GetHashCode()

Returns the hash code for this instance.

Returns
Type	Description
`int`	A 32-bit signed integer that is the hash code for this instance.

Overrides

ValueType.GetHashCode()

ToString()

public override string ToString()

Returns the fully qualified type name of this instance.

Returns
Type	Description
`string`	The fully qualified type name.

Overrides

ValueType.ToString()

Operators

operator ==(Blob, Blob)

public static bool operator ==(Blob lhs, Blob rhs)

Operator overload to compare two Blob values for equality.

Parameters
Name	Description
`lhs`	`Blob` Left value to compare
`rhs`	`Blob` Right value to compare

Returns
Type	Description
`bool`	true if `lhs` is equal to `rhs`; otherwise false.

operator !=(Blob, Blob)

public static bool operator !=(Blob lhs, Blob rhs)

Operator overload to compare two Blob values for inequality.

Parameters
Name	Description
`lhs`	`Blob` Left value to compare
`rhs`	`Blob` Right value to compare

Returns
Type	Description
`bool`	false if `lhs` is equal to `rhs`; otherwise true.
