Previously I talked about how to create a custom BizTalk pipeline component, and gave a few examples for accessing specific context properties. I wanted to be able to dump all the context properties to disk for examination, so I added a few lines of code and an on/off switch.
First, add two properties to your component:
private bool _EnableContextTrace;
private string _FileTraceLocation;
public bool EnableContextTrace
{
get { return _EnableContextTrace; }
set { _EnableContextTrace = value; }
}
public string FileTraceLocation
{
get { return _FileTraceLocation; }
set { _FileTraceLocation = value; }
}
Make sure to add them to the Load() and Save() methods in the IPersistPropertyBag region:
public virtual void Load(Microsoft.BizTalk.Component.Interop.IPropertyBag pb, int errlog)
{
object val = null;
val = this.ReadPropertyBag(pb, "EnableContextTrace");
if ((val != null))
this._EnableContextTrace = ((bool)(val));
val = this.ReadPropertyBag(pb, "FileTraceLocation");
if ((val != null))
this._FileTraceLocation = ((string)(val));
}
public virtual void Save(Microsoft.BizTalk.Component.Interop.IPropertyBag pb, bool fClearDirty, bool fSaveAllProperties)
{
this.WritePropertyBag(pb, "EnableContextTrace", this.EnableFileTrace);
this.WritePropertyBag(pb, "FileTraceLocation", this.FileTraceLocation);
}
And finally add some code to the Execute method to loop through all the context properties and write them to a text file:
if (_EnableContextTrace && _FileTraceLocation.Length > 0)
{
IBaseMessageContext contextList = inmsg.Context;
string name;
string nmspace;
string contextItems = "";
for (int x = 0; x < contextList.CountProperties; x++)
{
contextList.ReadAt(x, out name, out nmspace);
string value = contextList.Read(name, nmspace).ToString();
contextItems += "Name: " + name + " - " + "Namespace: " + nmspace + " - " + value + "\r\n";
}
using (StreamWriter outfile = new StreamWriter(_FileTraceLocation + "ContextProperties.txt"))
{
outfile.Write(contextItems);
}
}
After building the DLL and adding it to the Pipeline Components directory, you should be able to configure the properties:
Deploy the project, drop and file in, and examine the contents of the ContextProperties.txt file that was created. In my case I ran a HIPAA 837 file through and got the following:
