From(String, Encoding, SourceHashAlgorithm)

Source:

SourceText.cs

Constructs a SourceText from text in a string.

public static Microsoft.CodeAnalysis.Text.SourceText From (string text, System.Text.Encoding? encoding = default, Microsoft.CodeAnalysis.Text.SourceHashAlgorithm checksumAlgorithm = Microsoft.CodeAnalysis.Text.SourceHashAlgorithm.Sha1);

static member From : string * System.Text.Encoding * Microsoft.CodeAnalysis.Text.SourceHashAlgorithm -> Microsoft.CodeAnalysis.Text.SourceText

Public Shared Function From (text As String, Optional encoding As Encoding = Nothing, Optional checksumAlgorithm As SourceHashAlgorithm = Microsoft.CodeAnalysis.Text.SourceHashAlgorithm.Sha1) As SourceText

Parameters

text

String

Text.

encoding

Encoding

Encoding of the file that the text was read from or is going to be saved to. null if the encoding is unspecified. If the encoding is not specified the resulting SourceText isn't debuggable. If an encoding-less SourceText is written to a file a UTF8 shall be used as a default.

checksumAlgorithm

SourceHashAlgorithm

Hash algorithm to use to calculate checksum of the text that's saved to PDB.

Returns

SourceText

Exceptions

ArgumentNullException

text is null.

ArgumentException

checksumAlgorithm is not supported.

Parameters

reader

TextReader

length of content from reader

encoding

Encoding

Encoding of the file that the reader was read from or is going to be saved to. null if the encoding is unspecified. If the encoding is not specified the resulting SourceText isn't debuggable. If an encoding-less SourceText is written to a file a UTF8 shall be used as a default.

checksumAlgorithm

SourceHashAlgorithm

Hash algorithm to use to calculate checksum of the text that's saved to PDB.

Returns

SourceText

Exceptions

ArgumentNullException

reader is null.

ArgumentException

checksumAlgorithm is not supported.

Source:

SourceText.cs

Constructs a SourceText from stream content.

public static Microsoft.CodeAnalysis.Text.SourceText From (System.IO.Stream stream, System.Text.Encoding? encoding = default, Microsoft.CodeAnalysis.Text.SourceHashAlgorithm checksumAlgorithm = Microsoft.CodeAnalysis.Text.SourceHashAlgorithm.Sha1, bool throwIfBinaryDetected = false, bool canBeEmbedded = false);

Parameters

stream

Stream

Stream. The stream must be seekable.

encoding

Encoding

Data encoding to use if the stream doesn't start with Byte Order Mark specifying the encoding. UTF8 if not specified.

checksumAlgorithm

SourceHashAlgorithm

Hash algorithm to use to calculate checksum of the text that's saved to PDB.

throwIfBinaryDetected

Boolean

If the decoded text contains at least two consecutive NUL characters, then an InvalidDataException is thrown.

canBeEmbedded

Boolean

True if the text can be passed to FromSource(String, SourceText) and be embedded in a PDB.

Returns

SourceText

Exceptions

ArgumentNullException

stream is null.

ArgumentException

stream doesn't support reading or seeking. checksumAlgorithm is not supported.

DecoderFallbackException

If the given encoding is set to use a throwing decoder as a fallback

InvalidDataException

Two consecutive NUL characters were detected in the decoded text and throwIfBinaryDetected was true.

IOException

An I/O error occurs.

Remarks

Reads from the beginning of the stream. Leaves the stream open.

SourceText

The decoded text.

Exceptions

ArgumentNullException

The buffer is null.

ArgumentOutOfRangeException

The length is negative or longer than the buffer.

ArgumentException

checksumAlgorithm is not supported.

DecoderFallbackException

If the given encoding is set to use a throwing decoder as a fallback

InvalidDataException

Two consecutive NUL characters were detected in the decoded text and throwIfBinaryDetected was true.
