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);
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

Exceptions

text is null.

checksumAlgorithm is not supported.

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);

Public Shared Function From (stream As Stream, Optional encoding As Encoding = Nothing, Optional checksumAlgorithm As SourceHashAlgorithm = Microsoft.CodeAnalysis.Text.SourceHashAlgorithm.Sha1, Optional throwIfBinaryDetected As Boolean = false, Optional canBeEmbedded As Boolean = false) As SourceText

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

Exceptions

stream is null.

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

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

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

An I/O error occurs.

Remarks

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

buffer
Byte[]

The encoded source buffer.

length
Int32

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

The decoded text.

Exceptions

The buffer is null.

The length is negative or longer than the buffer.

checksumAlgorithm is not supported.

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

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