BinData C# Reference Documentation

BinData

Container for binary data. Provides methods for getting, setting, appending, etc. in binary and string encoded formats.

Object Creation

Chilkat.BinData obj = new Chilkat.BinData();

Properties

public bool LastMethodSuccess {get; set; }

Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of true indicates success, a value of false indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = true and failure = false.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to true. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

public int NumBytes {get; }

Introduced in version 9.5.0.51

The number of bytes contained within the object.

Methods

public bool AppendBd(BinData binData);

Introduced in version 9.5.0.62

Appends the contents of another BinData to this object.

Returns true for success, false for failure.

public bool AppendBinary(byte[] data);

Introduced in version 9.5.0.51

Appends binary data to the current contents, if any.

Returns true for success, false for failure.

public bool AppendBom(string charset);

Introduced in version 9.5.0.62

Appends the appropriate BOM (byte order mark), also known as a "preamble", for the given charset. If the charset has no defined BOM, then nothing is appended. An application would typically call this to append the utf-8, utf-16, or utf-32 BOM.

Returns true for success, false for failure.

public bool AppendEncoded(string encData, string encoding);

Introduced in version 9.5.0.51

Appends encoded binary data to the current data. The encoding may be "Base64", "modBase64", "base64Url", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", or any of the encodings found at Chilkat Binary Encodings List.

Returns true for success, false for failure.

public bool AppendEncodedSb(StringBuilder sb, string encoding);

Introduced in version 9.5.0.62

Decodes the contents of sb and appends the decoded bytes to this object. The encoding may be "Base64", "modBase64", "base64Url", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", or any of the encodings found at Chilkat Binary Encodings List.

Returns true for success, false for failure.

public bool AppendSb(StringBuilder sb, string charset);

Introduced in version 9.5.0.62

Appends the contents of a StringBuilder to this object.

Returns true for success, false for failure.

public bool AppendString(string str, string charset);

Introduced in version 9.5.0.62

Appends a string to this object. (This does not append the BOM. If a BOM is required, the AppendBom method can be called to append the appropriate BOM.)

Returns true for success, false for failure.

public bool Clear();

Introduced in version 9.5.0.51

Clears the contents.

Returns true for success, false for failure.

public bool ContentsEqual(BinData binData);

Introduced in version 9.5.0.62

Return true if the contents of this object equals the contents of binData.

public byte[] GetBinary();

Introduced in version 9.5.0.51

Retrieves the binary data contained within the object.

Returns an empty byte array on failure

public byte[] GetBinaryChunk(int offset, int numBytes);

Introduced in version 9.5.0.51

Retrieves a chunk of the binary data contained within the object.

Returns an empty byte array on failure

public string GetEncoded(string encoding);

Introduced in version 9.5.0.51

Retrieves the binary data as an encoded string. The encoding may be "Base64", "modBase64", "base64Url", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", or any of the encodings found at Chilkat Binary Encodings List.

Returns null on failure

public string GetEncodedChunk(int offset, int numBytes, string encoding);

Introduced in version 9.5.0.51

Retrieves a chunk of the binary data and returns it in encoded form. The encoding may be "Base64", "modBase64", "base64Url", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", or any of the encodings found at Chilkat Binary Encodings List.

public bool GetEncodedSb(string encoding, StringBuilder sb);

Introduced in version 9.5.0.64

Writes the encoded data to a StringBuilder. The encoding may be "Base64", "modBase64", "base64Url", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", or any of the encodings found at Chilkat Binary Encodings List.

public string GetString(string charset);

Introduced in version 9.5.0.67
