Converting usage of VB6 err object to C#
0
Below is my vb6 code how can i convert this into c#, Actually i'm getting confusion in that handling of err in if condition.
Function FilterDuplicates(Arr As Variant) As Long
Dim col As Collection, Index As Long, dups As Long
Set col = New Collection
On Error Resume Next
For Index = LBound(Arr) To UBound(Arr)
col.Add 0, CStr(Arr(Index))
If err Then
Arr(Index) = Empty
dups = dups + 1
err.Clear
ElseIf dups Then
Arr(Index - dups) = Arr(Index)
Arr(Index) = Empty
End If
Next
FilterDuplicates = dups End Function
Below is my C# Code which i tried and here actually i'm unable to handle this If condition part.
private long FilterDuplicates(string Arr)
{
Collection col = new Collection();
long Index=0;
long dups =0;
try
{
for (Index = Arr.GetLowerBound(0); Index <= Arr.GetUpperBound(0); Index++)
{
col.Add(0, Conversion.Str(Arr[Index]));
if (Information.Err)
{
Arr[Index] = null;
dups += 1;
err.Clear;
}
else if (dups != 0)
{
Arr[Index - dups] = Arr[Index];
Arr[Index] = null;
}
}
return dups;
}
catch
{
}
}

It's usually best to be specific about the exception types you intend to catch. See the docs and more docs for some examples.

sure you can handle an error and log it or whatever, then use thecontine.

I don't know how to handle the exception with a for loop, actually i want to increase the count of dups and have to make a error handler clear so it will run until for loop

What is the initial routine suppose to do? Often it's by far easier to implement a method than convert it: e.g. to count duplicatesArr.Length() - Arr.Distinct().Count();, get rid of duplicates:Arr.Distinct.ToArray();etc.

Often it's easier to implement the routine than convert it. It seems, you want
- Change each duplcate (i.e. second, third etc value) into
null
- Count all such changes
If it's your case, you can try
private static long FilterDuplicates(string Arr) {
HashSet<string> appeared = new HashSet<string>();
long result = 0;
for (int i = 0; i < Arr.Length; ++i)
if (!appeared.Add(Arr[i])) {
result += 1;
Arr[i] = null;
}
return result;
}
