Methods

CopyFrom(ReadOnlySpan<Byte>)

public static ByteString CopyFrom(ReadOnlySpan<byte> bytes)

Constructs a ByteString from a read only span. The contents are copied, so further modifications to the span will not be reflected in the returned ByteString.

Parameter
Name	Description
`bytes`	`ReadOnlySpan<Byte>`

Returns
Type	Description
`ByteString`

CopyFrom(Byte[])

public static ByteString CopyFrom(params byte[] bytes)

Constructs a ByteString from the given array. The contents are copied, so further modifications to the array will not be reflected in the returned ByteString. This method can also be invoked in ByteString.CopyFrom(0xaa, 0xbb, ...) form which is primarily useful for testing.

Parameter
Name	Description
`bytes`	`Byte[]`

Returns
Type	Description
`ByteString`

CopyFrom(Byte[], Int32, Int32)

public static ByteString CopyFrom(byte[] bytes, int offset, int count)

Constructs a ByteString from a portion of a byte array.

Parameters
Name	Description
`bytes`	`Byte[]`
`offset`	`Int32`
`count`	`Int32`

Returns
Type	Description
`ByteString`

CopyFrom(String, Encoding)

public static ByteString CopyFrom(string text, Encoding encoding)

Creates a new ByteString by encoding the specified text with the given encoding.

Parameters
Name	Description
`text`	`String`
`encoding`	`Encoding`

Returns
Type	Description
`ByteString`

CopyFromUtf8(String)

public static ByteString CopyFromUtf8(string text)

Creates a new ByteString by encoding the specified text in UTF-8.

Parameter
Name	Description
`text`	`String`

Returns
Type	Description
`ByteString`

CopyTo(Byte[], Int32)

public void CopyTo(byte[] array, int position)

Copies the entire byte array to the destination array provided at the offset specified.

Parameters
Name	Description
`array`	`Byte[]`
`position`	`Int32`

CreateCodedInput()

public CodedInputStream CreateCodedInput()

Creates a CodedInputStream from this ByteString's data.

Returns
Type	Description
`CodedInputStream`

Equals(ByteString)

public bool Equals(ByteString other)

Compares this byte string with another.

Parameter
Name	Description
`other`	`ByteString` The ByteString to compare this with.

Returns
Type	Description
`Boolean`	`true` if `other` refers to an equal byte string; `false` otherwise.

Equals(Object)

public override bool Equals(object obj)

Compares this byte string with another object.

Parameter
Name	Description
`obj`	`Object` The object to compare this with.

Returns
Type	Description
`Boolean`	`true` if `obj` refers to an equal ByteString; `false` otherwise.

FromBase64(String)

public static ByteString FromBase64(string bytes)

Constructs a ByteString from the Base64 Encoded String.

Parameter
Name	Description
`bytes`	`String`

Returns
Type	Description
`ByteString`

FromStream(Stream)

public static ByteString FromStream(Stream stream)

Constructs a ByteString from data in the given stream, synchronously.

Parameter
Name	Description
`stream`	`Stream` The stream to copy into a ByteString.

Returns
Type	Description
`ByteString`	A ByteString with content read from the given stream.

Remarks

If successful, stream will be read completely, from the position at the start of the call.

FromStreamAsync(Stream, CancellationToken)

public static Task<ByteString> FromStreamAsync(Stream stream, CancellationToken cancellationToken = null)

Constructs a ByteString from data in the given stream, asynchronously.

Parameters
Name	Description
`stream`	`Stream` The stream to copy into a ByteString.
`cancellationToken`	`CancellationToken` The cancellation token to use when reading from the stream, if any.

Returns
Type	Description
`Task<ByteString>`	A ByteString with content read from the given stream.

Remarks

If successful, stream will be read completely, from the position at the start of the call.

GetEnumerator()

public IEnumerator<byte> GetEnumerator()

Returns an iterator over the bytes in this ByteString.

Returns
Type	Description
`IEnumerator<Byte>`	An iterator over the bytes in this object.

Returns
Type	Description
`String`	The result of decoding the binary data with the given decoding.

Remarks

This method should only be used to convert binary data which was the result of encoding text with UTF-8.
