Hallo,
da gibt es verschiedene Möglichkeiten typisierte Daten zu schreiben/lesen.
| C++: |
private struct CACHE{
public Int32 dummy1;
public Int32 dummy2;
public Int32 noch_ein_Ddword;
public Int32 ok_genug;
}
private const int max = 4;
private CACHE[] tmp = new CACHE[max];
private string pfad ="cache.dat";
private void Form1_Load(object sender, System.EventArgs e)
{
int counter = 100;
for(int i=0; i < max; i++)
{
tmp[i].dummy1 = counter;
counter++;
tmp[i].dummy2 = counter;
counter++;
tmp[i].noch_ein_Ddword = counter;
counter++;
tmp[i].ok_genug = counter;
counter++;
}
}
private void btnWrite_Click(object sender, System.EventArgs e)
{
writeFile();
}
private void writeFile()
{
FileStream wStream = new FileStream(pfad,FileMode.OpenOrCreate,FileAccess.Write);
BinaryWriter bWriter = new BinaryWriter(wStream);
for(int i=0; i < max; i++)
{
bWriter.Write(tmp[i].dummy1);
bWriter.Write(tmp[i].dummy2);
bWriter.Write(tmp[i].noch_ein_Ddword);
bWriter.Write(tmp[i].ok_genug);
}
bWriter.Flush();
bWriter.Close();
wStream.Close();
}
private void btnRead_Click(object sender, System.EventArgs e)
{
for(int i =0; i < max; i++)
{
tmp[i].dummy1 = 0;
tmp[i].dummy2 = 0;
tmp[i].noch_ein_Ddword = 0;
tmp[i].ok_genug = 0;
}
readFile();
}
private void readFile()
{
FileStream rStream = new FileStream(pfad,FileMode.OpenOrCreate,FileAccess.Read);
BinaryReader bReader = new BinaryReader(rStream);
for (int i=0; i < max; i++)
{
tmp[i].dummy1 = bReader.ReadInt32();
tmp[i].dummy2 = bReader.ReadInt32();
tmp[i].noch_ein_Ddword = bReader.ReadInt32();
tmp[i].ok_genug = bReader.ReadInt32();
}
bReader.Close();
rStream.Close();
}
