C#中关于struct的问题，百思不得其解？？？？？

Question

就是说out参数必须在调用的时候被赋值
你可以在函数的第一句话加上userDataRight = ??;这样的赋值语句
这和struct无关的

Answer 1

public void UserValRight(out UserDataRight userDataRight){
try
{
//此处连接数据库部分省略              SqlDataReader userGroupRecord=cmdUserRight.ExecuteReader();
                      //初始化权限                        usetDataRight = new UserDataRight();//add this sentence 
  
                           userDataRight.UserAddRight=false;
                           userDataRight.UserDelRight=false;
userDataRight.UserEditRight=false;
userDataRight.UserSaveRight=false;
userDataRight.UserSelRight=false; 
                        while(userGroupRecord.Read()){
//判断是否有查询权限
if(userGroupRecord.GetValue(3).ToString()=="1"){
userDataRight.UserSelRight=true; 
          }
                            
               }
      userGroupRecord.Close(); }////////////////////调用部分的代码是UserCharacter userRightCharacter=new UserCharacter("001");
         UserDataRight userDataRights;
//userDataRights=new UserDataRight();
userRightCharacter.UserValRight(out userDataRights); 
if(userDataRights.UserSelRight==true)
       {
MessageBox.Show("有新增权限");
}else{
MessageBox.Show("sdddd");
}
