I'm using this method, I'm having difficulty.

int [] ReadWriteMultipleRegisters (int startingAddressRead, int   quantityRead, int startingAddressWrite, int [] values)

Read / Write Multiple Registers (Function code 23).

startingAddressRead: First input register to read.

quantityRead: Number of input registers to read.

startingAddressWrite: First input register to write.

values: Values to write.

returns: Int Array which contains the holding registers   [0..quantityRead-1].

I'm having an error assigning the variable int[] values , they could help me.

Thank you.

how it says alanfcm in the comments, you are misplacing the variable writeData , your function expects a int[] and you send a int

//Declaración de variables
int startingAddressRead = 0, quantityRead = 0, startingAddressWrite = 0;
int[] values = new int[5];
//Llamada a la función y almacenado el retorno en 'resultado'
var resultado = ReadWriteMultipleRegisters(startingAddressRead, quantityRead, startingAddressWrite, values);

//Función de ejemplo
int[] ReadWriteMultipleRegisters(int startingAddressRead, int quantityRead, int startingAddressWrite, int[] values) => new int[2];

As you can see in the code snippet, you should have no problem calling your function.
