Hi,
BadTypeMismatch means that the datatype of the variable you were trying to write to does not match what you are writing, without more information (like actual parameters values and some information about the server) that is about all I can provided.

Hi Paul,
Thanks for helping.
I ‘m testing my client with Opc Ua Quickstart Data Access Server. Following is the code with parameters and values that I’m used. pls help
WriteValueCollection nodesToWrite = new WriteValueCollection();
WriteValue writeValue = new WriteValue();
NodeId nodeId = "ns=2;s=1:FC1001?SetPoint";
writeValue.AttributeId = Attributes.Value;
writeValue.IndexRange = null;
object objvalue = 400.5F;
DataValue dataValue = new DataValue()
{
WrappedValue = 400.5F,
SourceTimestamp = DateTime.Now,
Value = objvalue
};
writeValue.Value.Value = dataValue;
writeValue.Value.StatusCode = StatusCodes.Good;
writeValue.Value.ServerTimestamp = DateTime.MinValue;
writeValue.Value.SourceTimestamp = DateTime.MinValue;
nodesToWrite.Add(writeValue);
foreach (WriteValue nodeToWrite in nodesToWrite)
{
NumericRange indexRange;
ServiceResult result = NumericRange.Validate(nodeToWrite.IndexRange, out indexRange);
if (ServiceResult.IsGood(result) && indexRange != NumericRange.Empty)
{
// apply the index range.
object valueToWrite = nodeToWrite.Value.Value;
result = indexRange.ApplyRange(ref valueToWrite);
if (ServiceResult.IsGood(result))
{
nodeToWrite.Value.Value = valueToWrite;
}
}
}
StatusCodeCollection results = null;
DiagnosticInfoCollection diagnosticInfos = null;
ResponseHeader responseHeader = m_session.Write(
null,
nodesToWrite,
out results,
out diagnosticInfos);
Thank you..
