c# JavaScriptSerializer deserialize variable type field

Question

I am trying to deserialize JSON strings where some fields can be different. These are some of the strings I have to deserialize:

{"field1":{"array":[1,2,3]},"field2":{"array":["a","b","c"]}}

{"field1":"", "field2":""}

{"field1":"","field2":{"array":["a","b","c"]}}

{"field1":{"array":[1,2,3]},"field2":""}

The first string is successfully deserialized, but the remainder throws an exception.

Is it possible to parse the four strings with the same code?

Answer 1

The reason why the others are throwing an exception is most likely because your deserialization target data type is expecting an object inside field1 and field2, but in last three, you have empty strings.

Try replacing the empty strings with just null .
