“Property” : “{” “Value”: 1, “Other”: 2 “}”

Instead of:

“Property” : { “Value”: 1, “Other”: 2 }

I’ll post these as issues to git hub. For the time being i’ve used:

private static string ToInvariantString(this Document doc) {
var json = new StringBuilder();
json.Append(“{ “);
var first = true;

foreach (string key in doc.Keys) {
if (first) {
first = false;
} else {
json.Append(“, “);
}
json.AppendFormat(CultureInfo.InvariantCulture, @”"”{0}”": “, key);
SerializeType(doc[key], json);
}
json.Append(” }”);
return json.ToString();
}

private static void SerializeType(object value, StringBuilder json) {
if (value == null) {
json.Append(“null”);
return;
}
var t = value.GetType();
if (value is bool) {
json.Append(((bool)value) ? “true” : “false”);
} else if (t.IsArray) {
json.Append(“[ ");
var first = true;
foreach (var v in (Array)value) {
if (first) {
first = false;
} else {
json.Append(", ");
}
SerializeType(v, json);
}
json.Append(" ]“);
} else if (value is Document) {
json.Append(((Document)value).ToInvariantString());
} else if (value is Oid ||
value is int ||
value is Int32 ||
value is long ||
value is float ||
value is double) {
json.AppendFormat(CultureInfo.InvariantCulture, “{0}”, value);
} else if (value is DateTime) {
json.AppendFormat(@”"”{0}”"”, ((DateTime)value).ToUniversalTime().ToString(“o”));
} else {
json.AppendFormat(CultureInfo.InvariantCulture, @”"”{0}”"”, value);
}
return;
}

Which is about the same as the .ToString method on the document, with a few edits here and there

Hope this helps someone.

Post the issue at: http://github.com/samus/mongodb-csharp/issues

I’m currently trying to get some time to build by own driver but I don’t know if I will get enough time….

The issue has been corrected in Oid.ToString in the MongoDb-driver, but Sam was uncertain if it had reached the main-branch at Github.

Nice tip with the nested types.

//Daniel

Now, regarding the storing of arrays,

In the
protected virtual object ConvertToMongoDbValue(JToken token)
if (token.Type == JTokenType.Array)
{
var r = token.Select(j => (string)j).ToArray();
if (r == null || r.Length < 1)
return MongoDBNull.Value;

return r;
}

You could change it to:

if (value.Type == JTokenType.Array) {
var items = new List();

foreach (var v in value) {
var doc = PopulateDocumentFrom(new Document(), v.ToString());
items.Add(doc);
}

if (items.Count < 1)
return MongoDBNull.Value;

return items.ToArray();
}

Giving you the ability to store/retrieve nested types

I have just tested the following:

1. Downloaded my example from: http://files.wertheim.se/blog/Pls-Mdb-Intro.zip
2. Unziped
3. Opened in Visual Studio 2010
4. Started Mongodb (mongod -dbpath c:\MongoDB\Data -directoryperdb)
5. Ran the Pls.MdbIntro app (F5)
6. Worked without any exceptions.

Worked.

Do that and I will check it out.
