]Hi support team,

I am working over trial license before purchasing the license. I have faced with a problem while trying to write array values as "Input string was not in correct format". Please see the screenshot i attached in the link below.

Waiting for your reply,

Hi alipala

You can not write arrays with the sample client. Here is an example, how to write an array on the .net demoserver:

Code: Select all

List<WriteValue> nodesToWrite = new List<WriteValue>();

/* Set new values to write */
List<UInt32> newValues = new List<UInt32>(new UInt32[] { 0, 1, 2 });

Variant value = new Variant(newValues);

/* Add array to WriteValues */
nodesToWrite.Add(new WriteValue()
{
    NodeId = new NodeId("Demo.Static.Arrays.UInt32", 2),
    AttributeId = Attributes.Value,
    Value = new DataValue() { WrappedValue = value },
    IndexRange = "1:3" 
    });

 List<StatusCode> res = Session.Write(nodesToWrite);

/* Check result */
foreach (StatusCode result in res)
{
    if (result.IsBad())
    {
    //write failed
    }
}
