StreamReader MyReader=new StreamReader("...//...//filename.txt");
string line="";
int[,] a= new int[2,3];
int count=0;
while((line=MyReader.readLine())!=null)
{
char []sp=new char(1);
sp[0]=" ";
string []s=line.spilter(sp);
for(int i=0;i<=s.lenght-1;i++)
{ a[count,i]=int.parse(s[i]);

}
++count ;

}

filestream fs = new fs(filemodel.open);
bufferstream bf = new bufferstream(fs);
int[,] a= new int[2,3];
while((int num=bf.peek())!=-1)
{
for(int j=0;j<=a;j++)
{
for(int k=0;k<=3;k++)
{
a[j,k] = num;
}
}
}
