VisaualC# .hope some body will helpme out about this how can it be done
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

class grip: public wait<grip>

{

public:

int make[5];

int rate;

grip(int x, int y, int s, int d, int t, int v) {

make [0]=x; make [1]=y; make [2]=s; make [3]=d; make [4]=t;

rate=v;

new=NULL;

}

};

// Class used to store detections

class deceit : public wait < deceit >

{

public:

int x, y, s, orient, profile;

double output;

deceit (int xx, int yy, int ss, double o, int dir, int pr=0) {

x=xx; y=yy; s=ss; output=o; orient=dir; profile=pr;

}

};

template <class T>

class wait

{

public:

T *old, *new;

Assuming you are using C# 2.0, the following is a rough translation. If
you are on C# 1, templates are not supported and you'd have to implement
the whole hierarchy differently.

public class Wait<T> {
public T old, new;
}

public class Deceit : Wait<Deceit> {
public int x, y, s, orient, profile;
public double output;

public Deceit(int xx, int yy, int ss, double o, int dir, int pr) {
x = xx; y = yy; s = ss; output = o; orient = dir; profile = pr;
}

public Deceit(int xx, int yy, int ss, double o, int dir) :
this(xx, yy, ss, o, dir, 0) {
}
}

public class Grip: Wait<Grip> {
public int[] make = new int[5];
public int rate;

public Grip(int x, int y, int s, int d, int t, int v) {
make[0] = x; make[1] = y; make[2] = s; make[3] = d; make[4] = t;
rate = v;
new = null;
}
}

Now let me mention that this is horrible C# code... the least thing that
should be done is use properties instead of the public fields, and use
proper names for the variables and constructor parameters.

Why do you feel you have to use pointers and unsafe code here?

You can't take the address of a reference type variable such as Node.

Plain references.

public class Node
{
public Node pr;
public Node ne;
}

public class Element : Node
{
public Element fist;
public Element lst;
public int length;
}

and replace all -> with . in the code.
