Question

C#中好像有种变量比必须一下划线开头,什么变量是这样命名的?

关于C#的类,方法等变量命名法,我也不大清楚哦.希望也能讲解一下~

Answer 1

不是必须的，这样比较方便代码的编写，如下：
public class PCase
{
private int _CaseID;
private int _CaseSortID;
private string _Title;
private string _Picture;
private string _Depict;
private bool _IsVouch;

public int CaseID
{
get { return _CaseID; }
set { _CaseID = value; }
}
public int CaseSortID
{
get { return _CaseSortID; }
set { _CaseSortID = value; }
}
public string Title
{
get { return _Title; }
set { _Title = value; }
}
public string Picture
{
get { return _Picture; }
set { _Picture = value; }
}
public string Depict
{
get { return _Depict; }
set { _Depict = value; }
}
public bool IsVouch
{
get { return _IsVouch; }
set { _IsVouch = value; }
}
}

Answer 2

按照编程中的规则是private 私有的变量需要以'_'开头
但是在实际中可以不必遵守，但是使用规范会提高代码的可读性
所以建议还是尽量符合规则

Answer 3

没有必须的吧，私有变量习惯上这样，但是不必须

不是必须的，这样比较方便代码的编写，如下：
public
class
PCase
{
private
int

private
int
_CaseSortID;
private
string
_Title;
private
string
_Picture;
private
string
_Depict;
private
bool
_IsVouch;
public
int
CaseID
{
get
{
return
_CaseID;
}
set
{
_CaseID
=
value;
}
}
public
int
CaseSortID
{
get
{
return
_CaseSortID;
}
set
{
_CaseSortID
=
value;
}
}
public
string
Title
{
get
{
return
_Title;
}
set
{
_Title
=
value;
}
}
public
string
Picture
{
get
{
return

}
set
{
_Picture
=
value;
}
}
public
string
Depict
{
get
{
return

}
set
{
_Depict
=
value;
}
}
public
bool
IsVouch
{
get
{
return

}
}
}
