Hello,
thank you for your interest in our products.
For a list of available examples: Start -> OPC Labs -> QuickOPC 5.3 -> Examples (.NET Source Code) -> About Examples,
or

A VS solution with C# examples: Start -> OPC Labs -> QuickOPC 5.3 -> Examples (.NET Source Code) -> Visual C# Examples.
In that solution, reading of multiple OPC UA tags can be seen in following examples:
- Console -> UADocExamples -> _EasyUAClient.ReadMultiple.Main
- Console -> UADocExamples -> _EasyUAClient.ReadMultipleValues.Main
And here is an actual code snippet taken from one of the examples:
public static void Main()
{
// Instantiate the client object
var easyUAClient = new EasyUAClient();
// Obtain attribute data. By default, the Value attributes of the nodes will be read.
UAAttributeDataResult[] attributeDataResultArray = easyUAClient.ReadMultiple(new[]
{
new UAReadArguments("http://opcua.demo-this.com:51211/UA/SampleServer", "nsu=http://test.org/UA/Data/;i=10845"),
new UAReadArguments("http://opcua.demo-this.com:51211/UA/SampleServer", "nsu=http://test.org/UA/Data/;i=10853"),
new UAReadArguments("http://opcua.demo-this.com:51211/UA/SampleServer", "nsu=http://test.org/UA/Data/;i=10855")
});
// Display results
foreach (UAAttributeDataResult attributeDataResult in attributeDataResultArray)
Console.WriteLine("AttributeData: {0}", attributeDataResult.AttributeData);
// Example output:
//
//AttributeData: 51 {System.Int16} @11/6/2011 1:49:19 PM @11/6/2011 1:49:19 PM; Good
//AttributeData: -1993984 {System.Single} @11/6/2011 1:49:19 PM @11/6/2011 1:49:19 PM; Good
//AttributeData: Yellow% Dragon Cat) White Blue Dog# Green Banana- {System.String} @11/6/2011 1:49:19 PM @11/6/2011 1:49:19 PM; Good
}
I hope this helps
Best regards
