Question

I am facing the problem that using JSON to pass an object to C# and C# pass a string back to Java and then java deserialize it to a Map
BTW, the .net version is 3.5

Here is the problem

the java map JSON string is in this format:

{"key1":"value1","key2":"value2"}

but in C#, the dictionary is seralized to

[{"Key":"key1","Value":"value1"},{"Key":"key2","Value":"value2"}]

I just want find a way to do this:

1. for java Map JSON format, C# could deseralize it
2. for C#, find a way to seralize it to a java understandable format

Thanks

Try to use JavaScriptSerializer instead of DataContractJsonSerializer:

var dict = new Dictionary<string, string>
{
    { "key1", "value1" },
    { "key2", "value2" }
};
var jss = new JavaScriptSerializer();
string json = jss.Serialize(dict); // {"key1":"value1","key2":"value2"}
