using FlatBuffers; // ... FlatBufferBuilder builder = new FlatBufferBuilder(1024); int value = 42; // Add the integer value to the builder: var intValue = builder.CreateInt32(value);In this example, we first import the FlatBuffers library by using the `using` directive. We then create a new `FlatBufferBuilder` object, passing in a buffer size of 1024 bytes. Finally, we create an integer value `42` and add it to the builder using the `CreateInt32` method, which returns a `Offset
