Media Bin 4.5 Webservices .Net Search Examples

MattRazor

Does anybody have examples of searching metadata using the values array. When I pass in an array of strings, such as assets names, I get a SOAP exception everytime. Here is the XML of my soap request and code.


CODE:

MediaBinServer service = new MediaBinServer();
service.Url = "http://localhost:8081/MediaBinWebService/MediaBinServer.asmx";
Uri u = new Uri( "http://localhost:8081/MediaBinWebService/MediaBinServer.asmx");
CredentialCache cache = new CredentialCache();
cache.Add( u,"NTLM", new NetworkCredential( "user", "password", "DEV1"));
service.Credentials = cache;
MBContainer obj = service.GetRootContainer();
MBSearchCriteria criteria = new MBSearchCriteria();
criteria.mRecursive = true;
criteria.mContainerID = service.GetRootContainer().mID;
MBSearchConstraint constraint = new MBSearchConstraint();
MBMetadata data = new MBMetadata();
data.mID = "{B297C571-F083-11D4-8200-0060080D8AC2}";
constraint.mMetadata = data;
String[] values = {"Winter.jpg", "Sunset.jpg"};
constraint.mMetadata.mValues = values;
constraint.mSearchOperator = "Contains";
MBSearchConstraint[] constraints = {constraint};
criteria.mSearchConstraints = constraints;
MBAsset[] assetsSearch = service.Search(criteria, false);

That's not quite the way to go about it.

You don't create a MBMetadata object and then assign an ID to it, you get the object with a GetMetadata call...

I haven't tested this code (extracted it from an app that works and reworked it to make it more generic), but it should be fairly close to the mark:

MediaBinServer myMBServer
MBSearchCriteria searchCriteria;
MBSearchConstraint myConstraint2, myConstraint1, brandConstraint;
string strValue1, strValue2;
string strMetadata1ID, strMetadata2ID;

//Initialization of myMBServer not shown

strValue1 = "...";
strValue2 = "...";
strMetadata1ID = "{...}";
strMetadata2ID = "{...}";

myConstraint1 = new MBSearchConstraint();
myConstraint1.mMetadata = myMBServer.GetMetadata(strMetadata1ID);
myConstraint1.mMetadata.mValue = strValue1;
myConstraint1.mBooleanOperator = MBBooleanOperator.AND;
myConstraint1.mSearchOperator = "OpExists";

myConstraint2 = new MBSearchConstraint();
myConstraint2.mMetadata = myMBServer.GetMetadata(strMetadata2ID);
myConstraint2.mMetadata.mValue = strValue2;
myConstraint2.mBooleanOperator = MBBooleanOperator.NotSet;
myConstraint2.mSearchOperator = "OpExists";

searchCriteria = new MBSearchCriteria();
searchCriteria.mContainerID = ConfigurationHolder.ContainerID;
searchCriteria.mSearchConstraints = new MBSearchConstraint[2] {myConstraint1, myConstraint2};
searchCriteria.mMaxHits = 1000;
searchCriteria.mRecursive = true;

MBAsset[] result = myMBServer.Search(searchCriteria,false);
