There's nothing wrong with the code per se, it's likely the issue is with special characters that are in the variables you are using, such as apostrophes, quotes etc. If that's the case you'll need to encode them.

Why are you creating a JSON string in C# if you're just going to immediately parse it into an object?

Just create the HandShakeRequest object directly.

HandShakeRequest resultT2 = new HandShakeRequest
{
    BankId = bankId,
    UserName = userName,
    Password = password,
};

Solution 1

you can try below

var obj={};
obj.bankId=bankid;
obj.password=password ;
obj.userName=userName ;

string jsonstr2=JSON.stringify(obj);

and in C#

HandShakeRequest resultT2 =JsonConvert.DeserializeObject<HandShakeRequest>(jsonstr2)

you need to use Newtonsoft.Json for this

I am able to pass values concatenated fine for the first one. But second one getting invalid json delimiter

First one fine
string jsonstr = @"{""bankId"": 049, ""password"": ""P049563445634674574325323674we5476956789057905694565745764256456"", ""userName"":""6919301721649254400252100878956720265267481307739303873300957305"",""timestamp"":""10:00:00""}";

Output of first one which is fine:

{
"bankId": 1,
"password": "foo",
"signature": "",
"userName": "bar"
}

HandShakeRequest resultT = new JavaScriptSerializer().Deserialize<handshakerequest>(jsonstr);

Second one getting invalid json delimiter
string jsonstr2 = @"{'bankId':" + bankid + ",'password': " + password + ",'userName': " + userName + "}";

Output:
{
'bankId': 1,
'password': "foo",
'signature': "",
'userName': "bar"
}

Output of the second one which is getting issue as invalid json delimiter
string jsonstr2 = @"{'bankId':" + bankid + ",'password': " + password + ",'userName': " + userName + "}";

HandShakeRequest resultT = new JavaScriptSerializer().Deserialize<handshakerequest>(jsonstr);
