Failing to make a patch via API using c# and json

Question

I am using C# to call an API to make an update on a record. there is a class for this patch operation which has Op, Path, and Value defined as strings. However, the value needs to be passed as an array which has several items inside it. I can make this work via Postman, but cannot make it work in C#. This is my code below:

 

CustomerValue mycustomer = new CustomerValue();

{

mycustomer.Id = 5;

mycustomer.Caption = "Customer Testing";

mycustomer.Value = "Test value";

}

List<CustomerValue> cf = new List<CustomerValue>

{

mycustomer

};

 

string jsonstr = JsonConvert.SerializeObject(cf);

var client = getApiClient();

var custApi = new CustApi(client);

var patchOps = new List<PatchOp>

{

new PatchOp

{

Op = "replace",

Path = "/customFields",

Value = jsonstr

}

};

var pResponse = custApi.UpdateCustomer(custid, patchOps);

When I look at patchOps, I see a similar string to the json string I get from Postman except for one additional quote that wrap jsonstr on each side.

 

Example of Postman string:

[{\"op\":\"replace\",\"path\":\"/custFields\",\"value\":[{\"id\":5,\"caption\":\"Cust Rating\",\"type\":0,\"entryMethod\":1,\"numberOfDecimals\":0,\"value\":\"Red - Bad\"}]}]"

 

mine will have an additional \" before and after of each of the internal brackets.

 

Any help please?
