Why changed values in a foreach don't save?

[cit]

Yes, i do this (stupid) iteration-stuff only for testing ;-)

Thanks, you give me the solution. Sorry i normaly work with C#. At C# it's not a "copy". okay, i will do it by ref, because i like the 'foreach' ;-)

PS: what a stumbling block!!!!

I tried the "&", but i got an error.

//  int i=-1;
    foreach (FileEntry & itmFile, fileList)
    {
    //i++;
        if((tmpType=="alle")||(itmFile.type==tmpType))  //Stimmt Typ?
        {
            if(itmFile.size+currentSize<maxSize)        //Begrenzung noch nicht überschritten?
            {
                currentSize += itmFile.size;
                itmFile.selected=true;                  //wird ausgewählt
                //fileList[i].selected=true;
                continue;
            }
        }
        itmFile.selected=false;                         //wird nicht ausgewählt
        //fileList[i].selected=false;
    }
