Here you go Sebastien,

public class TestConstuctor
{
     public string myVarA;
     public string myVarB;
     public string myVarC;
     public string myVarD;

     public TestConstructor(string A)
     {
         this.myVar = A;
     }

     public TestConstructor(string A, string B):this(A)
     {
                  this.myVarB = B;
     }

     public TestConstructor(string A, string B, string C):this(A,B)
     {
         this.myVarC = C;
     }

     public TestConstructor(string A, string B, string C, string 
D):this(A,B,C)
     {
                this.myVarD = D;
     }
}

Another way to do this is have your last constructor do all of the work:

public class TestConstuctor
{
     public string myVarA;
     public string myVarB;
     public string myVarC;
     public string myVarD;

     public TestConstructor(string 
A):this(A,string.Empty,string.Empty,string.Empty){}

     public TestConstructor(string A, string 
B):this(A,B,string.Empty,string.Empty){}

     public TestConstructor(string A, string B, string 
C):this(A,B,C,string.Empty){}

     public TestConstructor(string A, string B, string C, string D){
                this.myVarA = A;
                this.myVarB = B;
                this.myVarC = C;
                this.myVarD = D;
     }
}
