AddJobs Method
Summary
Adds a batch of jobs to the JobProcessor database by calling the IJobService WCF Service.
Example
using LeadtoolsJobProcessorExamples.JobService;
//This method will be used to store the conversion settings (how the file should be converted).
//We will serialize it at the, and the worker assembly will deserialize it to obtain the settings.
public struct JobMetadata
{
public string SourceFile;
public string TargetFile;
public string Format;
public JobMetadata(string _sourceFile, string _targetFile, string _format)
{
SourceFile = _sourceFile;
TargetFile = _targetFile;
Format = _format;
}
}
//Serialize the job metadata to an xml string so it can be stored in the JobProcessor database,
//and deserialized later by the worker assembly when the job is processed.
public string SerializeToString(JobMetadata jobMetadata)
{
//Serialize the job metadata to an xml string so it can be stored in the JobProcessor database,
//and deserialized later by the worker assembly when the job is processed.

//The job metadata describes how the job should be converted. For this example, we will assume the worker assembly
//will convert image files from one format to another. We will create a struct (JobMetadata) to hold the conversion
//information, serialize it to a string, and add it as the job metadata. In a typical scenario, the worker assembly
//would receive the job metadata, deserialize it, and convert the file based on the properties in the JobMetadata
//struct.
