I am intending to serialise a two dimensional array. As recommended here to provide it as a jagged array, and compose it back from a jagged array:
[XmlIgnore]
public Rational[,] tab;
public Rational[][] Data
{
get
{
Rational[][] dt = new Rational[tab.GetLength(0)][];
for (int i = 0; i < tab.GetLength(0); i++)
{
dt[i] = new Rational[tab.GetLength(1)];
for (int j = 0; j < tab.GetLength(1); j++)
dt[i][j] = tab[i, j];
}
return dt;
}
set
{
tab = new Rational[ value.Length, value[0].Length ];
for (int i = 0; i < tab.GetLength(0); i++)
for (int j = 0; j < tab.GetLength(1); j++)
tab[i, j] = value[i][j];
}
}
The type Rational represents a fraction that can be in decimal float or a/b integers fraction format. I did separate serialisation for Rational, and it has no problem with this type.
I get this exception in the place where XmlSerializer is constructed:

It is thrown exactly in this place:
XmlSerializer serializer = new XmlSerializer(typeof(SistemEcuatii));
And here is the code containing the serializer
class SistemEcuatiiModel
{
string baza;
XmlSerializer serializer = new XmlSerializer(typeof(SistemEcuatii));
SistemEcuatii data;
public void WriteTo()
{
TextWriter writer = new StreamWriter(baza);
serializer.Serialize(writer, data);
writer.Close();
}
void LoadFromFile()
{
StreamReader streamer = new StreamReader(baza);
SistemEcuatii dt = (SistemEcuatii)serializer.Deserialize(streamer);
streamer.Close();
data = dt;
}

I tried suggestion from github issues, but still can't make it working
