## Frequently asked questions
|
|
|
|
### I occasionally get a NullReferenceException, what's wrong?
|
|
You probably don't check the result status of a call and just assume the data is always there. `NullReferenceExecption`s will happen when you have code like this `var symbol = client.GetTickersAync().Result.Data.Symbol` because the `Data` property is null when the call fails. Instead check if the call is successful like this:
|
|
```csharp
|
|
var tickerResult = await client.GetTickersAync();
|
|
if(!tickerResult.Success)
|
|
{
|
|
// Handle error
|
|
}
|
|
else
|
|
{
|
|
// Handle result, it is now safe to access the Data property
|
|
var symbol = tickerResult.Data.Symbol;
|
|
}
|
|
```
|

|
### The socket client stops sending updates after a little while
|
|
You probably didn't keep a reference to the socket client and it got disposed.
|
|
Instead of subscribing like this:
|
|
```csharp
|
|
private void SomeMethod()
|
|
{
|
|
var socketClient = new BinanceSocketClient();
|
|
socketClient.Spot.SubscribeToOrderBookUpdates("BTCUSDT", data => {
|
|
// Handle data
|
|
});
|
|
}
|
|
```
|
|
Subscribe like this:
|
|
```csharp
|
|
private BinanceSocketClient _socketClient = new BinanceSocketClient();
|
|
|
|
// .. rest of the class
|
|
|
|
private void SomeMethod()
|
|
{
|
|
_socketClient.Spot.SubscribeToOrderBookUpdates("BTCUSDT", data => {
|
|
// Handle data
|
|
});
|
|
}
|
|
|
|
```
|
|
|
|
### Can I use the TestNet/US/other API with this library
|
|
Yes, generally these are all supported and can be configured by setting the BaseAddress in the client options. Some known API addresses should be available in the [Exchange]ApiAddresses class. For example:
|
|
```csharp
|
|
var client = new BinanceClient(new BinanceClientOptions
|
|
{
|
|
SpotApiOptions = new BinanceApiClientOptions
|
|
{
|
|
BaseAddress = BinanceApiAddresses.TestNet.RestClientAddress
|
|
},
|
|
UsdFuturesApiOptions = new BinanceApiClientOptions
|
|
{
|
|
BaseAddress = BinanceApiAddresses.TestNet.UsdFuturesRestClientAddress
|
|
}
|
|
});
|
|
```
|
|
|
|
### How are timezones handled / Timestamps are off by xx
|
|
Exchange API's treat all timestamps as UTC, both incoming and outgoing. The client libraries do no conversion so be sure to use UTC as well. |
