Question

Below is the code:

PropertyInfo[] requestPropertyInfo;
requestPropertyInfo = typeof(CBNotesInqAndMaintRequest).GetProperties();

The CBNotesInqAndMaintRequest contains request data member noteline1—noteline18. once I read the name of one of the data member, I want to get its last index. For eg. If the name of the request object is "noteline8", I want to get the index as 8.

For this I have written the below code:

foreach (PropertyInfo reqPropertyInfo in requestPropertyInfo)
{
  index = reqPropertyInfo.Name.LastIndexOf("noteline");
}

But the above code is returning the index as 0.

Answer 1

I created a RegEx solution that doesn’t matter what the property name is, but grabs the last digits and returns an integer

static int GetLastInteger( string name ) {

    int value;
    if( int.TryParse( name, out value ) ) {
        return value;
    }
    System.Text.RegularExpressions.Regex r = 
        new System.Text.RegularExpressions.Regex( @"[^0-9](\d+\b)" );

    System.Text.RegularExpressions.Match m = 
        r.Match( name );

    string strValue = m.Groups[1].Value;
    value = ( int.Parse( strValue ) );
    return value;
}

Usable in your example like so:

foreach (PropertyInfo reqPropertyInfo in requestPropertyInfo)
{
  index = GetLastInteger(reqPropertyInfo.Name);
}
