I have the following code but I would like invoke

Select(GetID(with parameters).

 double GetID(ID id)
{
 
double mId;
mId = id.getId(1, '0', 0, 10000);

return mId;
}
 maxID = dataFile.PaternMatching(objId).Select(GetID).Max();

I would like have the following instead

 double GetID(ID id, , int a, char c, int b, int d)
 {

double mId;
mId = id.getId(a, c, b, d);
return mId;

}

 maxID = dataFile.PaternMatching(objId).Select(GetID(1, '0', 0, 10000)).Max();

What I have tried:

 double GetID(ID id, , int a, char c, int b, int d)
 {

double mId;
mId = id.getId(a, c, b, d);
return mId;

}

 maxID = dataFile.PaternMatching(objId).Select(GetID(1, '0', 0, 10000)).Max();

Your question isn't entirely clear, but I think you're looking for a lambda method:

C#

maxID = dataFile.PaternMatching(objId).Select(id => GetID(id, 1, '0', 0, 10000)).Max();
