POReading null values in a byte array c#
text
Body
copied!<p>I am trying to loop through a byte array (sample below) reading the values to then insert those into a database</p> <p>I loop through keeping track of the position </p> <pre><code>byte[] data; position = Conversion.Extract(data, out mydata, position); position = Conversion.Extract(data, out nextitem, position); </code></pre> <p>The data I have contains some null values, how can I extract these and successfully move onto the next value. At present if I come across a null value I don't know how to detect this and move onto the next item. Can anyone help at all</p> <p>The Extract code is:</p> <pre><code>byte[] data; long position=0; while (position < data.Length) { position = Conversion.Extract(data, out mydata, position); position = Conversion.Extract(data, out nextitem, position); } public static long Extract(byte[] message, out int variable, long position) { const int length = 4; // the length of an int if (message.Length >= position + length) { variable = BitConverter.ToInt32(message, (int)position); return position + length; } variable = 0; return -1; } </code></pre> <p>Thanks</p> <p>Simon</p> <pre>6F 72 67 61 6E 69 73 61 74 69 6F 6E 49 64 3D 33 26 10 00 00 00 50 65 6F 70 6C 65 50 65 6F 70 6C 65 4C 69 6E 6B 6A 08 00 00 09 00 00 00 0E 00 00 00 53 65 6E 69 6F 72 50 65 72 73 6F 6E 49 64 0E 00 00 00 4A 75 6E 69 6F 72 50 65 72 73 6F 6E 49 64 11 00 00 00 53 65 6E 69 6F 72 50 65 72 73 6F 6E 4D 69 73 49 64 11 00 00 00 4A 75 6E 69 6F 72 50 65 72 73 6F 6E 4D 69 73 49 64 08 00 00 00 4C 69 6E 6B 54 79 70 65 16 00 00 00 50 61 72 65 6E 74 61 6C 52 65 73 70 6F 6E 73 69 62 69 6C 69 74 79 08 00 00 00 50 72 69 6F 72 69 74 79 0B 00 00 00 4C 61 73 74 55 70 64 61 74 65 64 07 00 00 00 44 65 6C 65 74 65 64 01 00 00 00 D7 0A 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 80 C3 29 C6 85 BF CE 08 00 02 00 00 00 3C 0C 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 F0 83 76 C6 85 BF CE 08 00 03 00 00 00 3C 0C 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 C0 0E 76 C6 85 BF CE 08 00 04 00 00 00 67 0B 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 70 CA 4B C6 85 BF CE 08 00 05 00 00 00 67 0B 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 70 CA 4B C6 85 BF CE 08 00 06 00 00 00 9B 08 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 C0 BE B2 C5 85 BF CE 08 00 06 00 00 00 AD 09 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 10 6D F5 C5 85 BF CE 08 00 06 00 00 00 3F 0A 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 80 59 11 C6 85 BF CE 08 00 07 00 00 00 E3 0A 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 C0 D0 2C C6 85 BF CE 08 00 08 00 00 00 9B 08 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 C0 BE B2 C5 85 BF CE 08 00 08 00 00 00 AD 09 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 10 6D F5 C5 85 BF CE 08 00 08 00 00 00 C9 09 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 20 76 FA C5 85 BF CE 08 00 08 00 00 00 3F 0A 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 B0 CE 11 C6 85 BF CE 08 00 09 00 00 00 E3 0A 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 90 5B 2C C6 85 BF CE 08 00 0A 00 00 00 C9 09 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 20 76 FA C5 85 BF CE 08 00 0B 00 00 00 F6 08 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 E0 C9 D2 C5 85 BF CE 08 00 0C 00 00 00 F6 08 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 F0 2C C9 C5 85 BF CE 08 00 0E 00 00 00 91 09 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 C0 C7 EF C5 85 BF CE 08 00 0F 00 00 00 91 09 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 90 52 EF C5 85</pre> <pre>SeniorPersonId | JuniorPersonId | SeniorPersonMisId | JuniorPersonMisId | LinkType | ParentalResponsibility | Priority | LastUpdated Deleted 1 | 2775 | {null} | {null} | {null} | 0 | 1 | 2012-02-22 14:31:18.200 | {null} 2 | 3132 | {null} | {null} | {null} | 0 | {null} | 2012-02-22 14:31:18.703 | {null} 3 | 3132 | {null} | {null} | {null} | 0 | {null} | 2012-02-22 14:31:18.700 | {null} 4 | 2919 | {null} | {null} | {null} | 0 | 1 | 2012-02-22 14:31:18.423 | {null}</pre>
