How do I find part of the unknown text in the attribute table?

string

Good day,
I'm trying to use c # to find in the attribute table the text for which I only know the beginning and I would need to find all the values ​​that correspond to it.
The code itself is not a problem, I just don't know how to replace the part I don't know.


Thank you all for your advice.

What I have tried:

protected override async void OnClick()
{
await QueuedTask.Run(() =>
{
FeatureLayer fl = MapView.Active.Map.FindLayers("O_Klad_ZTM10").First() as FeatureLayer;
QueryFilter qf = new QueryFilter();
string whereClause = "ZTM10_nom = '0602-***'"; //stars mean the part I don't know
qf.WhereClause = whereClause;

using (RowCursor rowCursor = fl.Search(qf))
{
while (rowCursor.MoveNext())
{
fl.Select(qf);
}
}
});
}

for example the text looks like: 0301-A-01,....., 0602-A-01,0602-A-02, ..., 0809-D-09
