// This example assumes the Chilkat HTTP API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();

// Insert your access key here:
http.AwsAccessKey = "AWS_ACCESS_KEY";

// Insert your secret key here:
http.AwsSecretKey = "AWS_SECRET_KEY";

// In this example, my bucket is "chilkat100".
// It contains a number of folders, one of which is named "images".
// I want to get a list of all sub-folders under the "images" folder
string strXml = http.S3_ListBucketObjects("chilkat100?prefix=images/&delimiter=/");
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

Debug.WriteLine("Response status code = " + Convert.ToString(http.LastStatus));

Chilkat.Xml xml = new Chilkat.Xml();
bool success = xml.LoadXml(strXml);
if (success != true) {
    Debug.WriteLine(xml.LastErrorText);
    return;
}

// If the response status code was not 200, then the XML response is not a 
// listing of objects, but instead contains error information.
if (http.LastStatus != 200) {
    Debug.WriteLine(xml.GetXml());
    Debug.WriteLine("Failed.");
    return;
}

// A sample response is shown below.
Debug.WriteLine(xml.GetXml());
Debug.WriteLine("----");

// Here is the list of sub-folders (i.e. CommonPrefixes)

// <?xml version="1.0" encoding="UTF-8"?>
// <ListBucketResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
//     <Name>chilkat100</Name>
//     <Prefix>images/</Prefix>
//     <Marker/>
//     <MaxKeys>1000</MaxKeys>
//     <Delimiter>/</Delimiter>
//     <IsTruncated>false</IsTruncated>
//     <CommonPrefixes>
//         <Prefix>images/africa/</Prefix>
//     </CommonPrefixes>
//     <CommonPrefixes>
//         <Prefix>images/sea_creatures/</Prefix>
//     </CommonPrefixes>
// </ListBucketResult>

string Prefix;

// The XML can be parsed like this:
int i = 0;
int count_i = xml.NumChildrenHavingTag("CommonPrefixes");
while (i < count_i) {
    xml.I = i;
    Prefix = xml.GetChildContent("CommonPrefixes[i]|Prefix");
    Debug.WriteLine("Prefix = " + Prefix);
    i = i + 1;
}
