Java to C#

[Zoomlion]

I have the following classes in Java which i want to convert to C# but have errors with the undelined codes. (Can someone help me with the C# equivalent of PUT and GET) class TagInfo{ public int tagOffset; public int tagLength; public TagInfo(){ } } private void buildMetaData() { Record record = getData(); int offset = IMGREC_TAGLIST_INDEX; int numTags = 0 ; short tagID = 0; try { numTags = this.getNumberOfTags() ; for (int i=0; i < numTags; i++){ TagInfo info = new TagInfo(); info.tagOffset = offset; info.tagLength = TagRecord.TAG_DATA_INDEX + record.readInt(offset + TagRecord.TAG_DATALEN_INDEX); tagID = record.readShort(offset + TagRecord.TAG_ID_INDEX); offset += info.tagLength; tagInfo.put(new Short(tagID),info); Console.WriteLine("tagID = " + tagID); } } catch (Exception ex) { } finally { } this.imageOffset = offset; this.imageSize = record.getLength() - offset; } public TagRecord getTagByID(short id) { TagRecord record = null; TagInfo info = (ImageRecord.TagInfo)tagInfo.get(new Short(id)); if (info != null){ byte[] data = this.getData().read(info.tagOffset,info.tagLength); record = new TagRecord(data); } return record; }

Those lines appear to be using a variable which does not exist. What is the type of tagInfo and where does it come from? It isn't a local variable or parameter or even a field in the class - so what is it?

Not to good at Java, but my understanding is that Put and Get operate on an automaticaly generated parent hashtable of the object in question. c# does not have this at all. You have to create your own dictionary. This might not be quite right as you did not post the entier code, but the following should help you. Note the dictionary declaration and add/get code. I have used a generic dictionary to enable strong typing.

class TagInfo{
public int tagOffset;
public int tagLength;

public TagInfo(){
}

}

// Dictionary to hold Taginfo Objects
System.Collections.Generic.Dictionary; TagInfoDictionary = new System.Collections.Generic.Dictionary();

private void buildMetaData()
{

Record record = getData();
int offset = IMGREC\_TAGLIST\_INDEX;
int numTags = 0 ;
short tagID = 0;

try
{
	numTags = this.getNumberOfTags() ;

	for (int i=0; i < numTags; i++){
		TagInfo info = new TagInfo();

		info.tagOffset = offset;
		info.tagLength = TagRecord.TAG\_DATA\_INDEX + record.readInt(offset + TagRecord.TAG\_DATALEN\_INDEX);
		tagID = record.readShort(offset + TagRecord.TAG\_ID\_INDEX);
		offset += info.tagLength;

		//	Add to the dictionary
		this.TagInfoDictionary.Add(tagID, info);

		Console.WriteLine("tagID = " + tagID);
	}
}catch (Exception ex){}
finally{}

this.imageOffset = offset;
this.imageSize = record.getLength() - offset;

}

public TagRecord getTagByID(short id)
{
TagRecord record = null;

//	Get from dictionary
TagInfo info = this.TagInfoDictionary\[id\];
if (info != null){
	byte\[\] data = this.getData().read(info.tagOffset,info.tagLength);
	record = new TagRecord(data);
}

return record;

}
