Hi,

can someone tell me the exact format of the Blob representing an Asset?

I tried a base64 decoding.

I obtain this

Reencoding base 64 with UTF8Encoding disrupts the gpstate file.

Can someone help me?

Thanks

Hi Marco,
you can read the gpstate using an XmlSerializer and the GuidancePackagesState* classes. Regarding the blob element is encoding using base64Binary.

I'm trying to add a new recipe to an old project. I have an old solution and I have modified some of the projects templates, so the old projects lack some new asset references I added to the new project template.

In .gpstate file I have something like this

<Reference>
<AssetName>DeployProcess</AssetName>
<AppliesTo>BLSpecific\BLSpecific11</AppliesTo> <Blob>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</Blob>
</Reference>

To add this reference to an old project in the solution I have changed the appliesto node innertext to the name of the old project and changed (with a binary editor)the project name into the base64 blob. Here is the new reference node

<Reference>
<AssetName>DeployProcess</AssetName>
<AppliesTo>BLSpecific\BLSpecific34</AppliesTo> <Blob>AAEAAAD/////AQAAAAAAAAAMAgAAAHNNaWNyb3NvZnQuUHJhY3RpY2VzLlJlY2lwZUZyYW1ld29yay5WaXN1YWxTdHVkaW8sIFZlcnNpb249MS4zLjAuMCwgQ3VsdHVyZT1uZXV0cmFsLCBQdWJsaWNLZXlUb2tlbj1iMDNmNWY3ZjExZDUwYTNhBQEAAABBTWljcm9zb2Z0LlByYWN0aWNlcy5SZWNpcGVGcmFtZXdvcmsuVmlzdWFsU3R1ZGlvLlByb2plY3RSZWZlcmVuY2UEAAAABWFzc2V0DnNvbHV0aW9uRm9sZGVyDElzV2ViUHJvamVjdARkYXRhAQAAAQEBAgAAAAYDAAAADURlcGxveVByb2Nlc3MAAAYEAAAAF0JMU3BlY2lmaWNcQkxTcGVjaWZpYzM0CwAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=</Blob>
</Reference>

I injected this reference node in the gpstate file and BLSpecific34 project now can run DeployProcess Recipe.

If I try using this code

string decodedASCII = base64DecodeASCII(blob);

decodedASCII = decodedASCII.Replace("BLSpecific11", "BLSpecific34");

string encodedASCII = base64EncodeASCII(decodedASCII);

private string base64DecodeASCII(string data)

{

try

{

System.Text.ASCIIEncoding encoder = new System.Text.ASCIIEncoding();

System.Text.Decoder asciiDecode = encoder.GetDecoder();

byte[] todecode_byte = Convert.FromBase64String(data);

int charCount = asciiDecode.GetCharCount(todecode_byte, 0, todecode_byte.Length);

char[] decoded_char = new char[charCount];

asciiDecode.GetChars(todecode_byte, 0, todecode_byte.Length, decoded_char, 0);

string result = new String(decoded_char);

return result;

}

catch (Exception e)

{

throw new Exception("Error in base64Decode" + e.Message);

}

}

private string base64EncodeASCII(string data)

{

try

{

byte[] encData_byte = new byte[data.Length];

encData_byte = System.Text.Encoding.ASCII.GetBytes(data);

string encodedData = Convert.ToBase64String(encData_byte);

return encodedData;

}

catch (Exception e)

{

throw new Exception("Error in base64Encode" + e.Message);

}

}

the new encoded blob cause an error loading the solution. Can you give me an help?

Hi Haplo,
Sorry for the delay, I'll try to reproduce your issue and I'll back to you as soon as possible.
