Howto write a class where a property can be accessed without naming it.
- by SchlaWiener
I have a (dump) question regarding VB/C#
I often use third party classes where I can access a child object with only specifying the id or key.
Example:
Instead of writing:
DataRow row = GetAPopulatedDataRowSomeWhere();
Object result = row.Items[1]; // DataRow has no Items property
Object result = row.Items["colName"]; // Also not possible
I use this code to access the members:
DataRow row = GetAPopulatedDataRowSomeWhere();
Object result = row[1];
Object result = row["colName"];
Can someone tell me how a class has to look like to support this syntax?
My own class has a Dictionary that I want to access this way.
MyClass["key"]; // <- that's what I want
MyClass.SubItems["key"]; // <- that's how I use it now
