Document Intelligence | Contract Model | C# SDK

Avni Bhatt 120

Hi,

I am trying to use this Pre-built Contract Model in C# SDK. It basically extracts:

Title - TEXT
ContractId - TEXT
Parties - LIST
ExecutionDate - TEXT
ExpirationDate - TEXT
RenewalDate - TEXT
Jurisdictions - TEXT

On the AI studio, it works fine, I can see the results in JSON too. When i try to embed the code in C# SDK, I get the results for all text type fields. However, For "Parties", its a list, so I am not able to find an easy way to find it.

I tried below code that works to get other fields:

foreach(AnalyzedDocument doc in result.Documents)

{

System.Collections.Generic.IReadOnlyDictionary<string, DocumentField> Fields = doc.Fields;

Fields ["EffectiveDate"].Content;

}

However, as the values corresponding to "Parties" is a List, its not available via Content directly.

Upon placing debugger, its found at below node which is very much nested.

How do I access it on code?

Hello @Avni Bhatt

It looks like you need to interact with this as an index page when the field is a collection

you can follow this Example

Example: the following should result in PageIndex = 3, LineIndex = 7, WordIndex = 12 "#/analyzeResult/readResults/3/lines/7/words/12" from DocumentResult "#/readResults/3/lines/7/words/12" from PageResult

Maybe, you can try something like this:

foreach (AnalyzedDocument doc in result.Documents)
{
    IReadOnlyDictionary<string, DocumentField> fields = doc.Fields;

    string effectiveDate = fields["EffectiveDate"].Content;

    if (fields.TryGetValue("Parties", out DocumentField partiesField) && partiesField.ValueType == DocumentFieldType.List)
    {
        var partiesList = new List<string>();
        foreach (var party in partiesField.AsList())
        {

            if (party.ValueType == DocumentFieldType.String)
            {
                partiesList.Add(party.AsString());
            }
        }

        // Now partiesList contains all the parties from the "Parties" field
        // You can process this...
		// And I don't know if parties is a sting list, but I'm assuming it is 😊


    }
}

I hope this can help you 😊

Hi João Ricardo Rodrigues De La Cruz Baptista ,

Thanks for the insights. Parties actually is another list of key value pair but your answer helped in right direction. I just added this in the code that you helped with.

Thanks again!

 if (Fields.TryGetValue("Parties", out DocumentField partiesField) && partiesField.FieldType == DocumentFieldType.List)
 {
     
     var partiesList = partiesField.Value.AsList();
     foreach (var parties in partiesList)
     {
         var myDictionary1 = parties.Value.AsDictionary();
         foreach (string str1 in myDictionary1.Keys)
         {
             Azure.AI.FormRecognizer.DocumentAnalysis.DocumentField correspondingValue1 = myDictionary1[str1];
             Console.WriteLine("Key: " + str1 + ", Value: " + correspondingValue1.Content);
         }
     }
}
