I just stumbled across this looking for something else and thought I might help.
You actually have it a little backwards. The creation of the new object is actually the last step in the process. You need to create a collection of PropertyValues() by creating each individual PropertyValue() and then adding them to the collection.
So something like this:
public static PropertyValue GetPropertyValue(int propertyDefId, object value)
{
//resolve property def by ID
PropertyDef propertyDef = Vault.PropertyDefOperations.GetPropertyDef(propertyDefId);
//create the property value with prop def ID and value
return GetPropertyValue(propertyDefId, propertyDef.DataType, value);
}
public static PropertyValue GetPropertyValue(int propertyDefId, MFDataType dataType, object value)
{
PropertyValue propertyValue = new PropertyValue();
propertyValue.PropertyDef = propertyDefId;
propertyValue.TypedValue.SetValue(dataType, value);
return propertyValue;
}
public static ObjectVersionAndProperties CreateDocument(PropertyValues propertyValues, string filepath, Vault vault)
{
// Create the Source File object from the filepath.
SourceObjectFile sourceFile = new SourceObjectFile();
sourceFile.SourceFilePath = filepath;
sourceFile.Extension = Path.GetExtension(filepath).TrimStart('.');
sourceFile.Title = Path.GetFileNameWithoutExtension(filepath).TrimEnd('.');
// Create the document object.
return vault.ObjectOperations.CreateNewSFDObject((int)MFBuiltInObjectType.MFBuiltInObjectTypeDocument,
propertyValues, sourceFile, true);
}
Once you set up the above functions you could call them like:
//If the document doesn't exist, go ahead and create a new one
//creat and add all the properties
PropertyValues props = new PropertyValues();
//class
props.Add(-1, HelperMF.GetClassPropertyValue(classId, env.Vault));
//job
int jobId = env.Vault.ValueListItemOperations.GetValueListItemByDisplayID(Structure.ObjType.Job.ID, jobDisplayId).ID;
props.Add(-1, HelperMF.GetPropertyValue(Properties.Job.ID, jobId, env.Vault));
//estimates
props.Add(-1, HelperMF.GetPropertyValueFromListOfDisplayIds(env.Vault, Properties.Estimate.ID,
MFDataType.MFDatatypeMultiSelectLookup, Structure.ObjType.Estimate.ID, estimateDisplayIds));
//Add the relationship to the return doc that was uploaded
props.Add(-1, HelperMF.GetPropertyValue(Properties.Document.ID, movingDocId, env.Vault));
//create the new object in the vault
ObjectVersionAndProperties newDoc = HelperMF.CreateDocument(props, docDownloadPath, env.Vault);
I use a lot of help functions and classes but you should get the gist from my samples. Also, I would highly recommend you use the M-Files community website for research as they have a lot of code samples there geared specifically for M-Files.

Also, if you don't already, use the API documentation as it also includes code samples.

Hopefully this helps,
