问题描述
我有一个类有2个构造函数:
code解决方案 > $ obj
$ b pre> public test(bool a, int b,string c)
:this(a,b)
{
this.m_C = c;
}
public Test(bool a,int b,float d)
:this(a,b)
{
this.m_D = d;
}
private Test(bool a,int b)
{
this.m_A = a;
this.m_B = b;
}
源由
I have a class with 2 constructors:
public class Lens { public Lens(string parameter1) { //blabla } public Lens(string parameter1, string parameter2) { // want to call constructor with 1 param here.. } }
I want to call the first constructor from the 2nd one. Is this possible in C#?
解决方案
Append :this(reqd params) at the end of the ctor to do 'constructor chaining'
public Test( bool a, int b, string c ) : this( a, b ) { this.m_C = c; } public Test( bool a, int b, float d ) : this( a, b ) { this.m_D = d; } private Test( bool a, int b ) { this.m_A = a; this.m_B = b; }
