如何在c＃中停止执行条件（if-loop） [英] How to stop execution of condition(if-loop) in c#

问题描述

您好我想停止if循环的执行，我已尝试使用'return'语句但它退出函数，那么如何退出单个if Statement.I尝试使用以下代码...

Hi I want to stop the execution of if-loop ,I have tried with 'return' statement but its exits from the function ,So how can I exit from the single if Statement.I have tried with following code...

void A()
{

          if (CheckHorizontalSide(SourceMember))
            {
                
                if (lblHorizontalMember.Text == DestinationMember)
                {
                    
                    lsRelationPath.Add(lblHorizontalMember.Text);
                    lblRelationPath.Text = String.Join("-", lsRelationPath);
                    lblRelationPath.Visible = true;
                    return;
                }

                bool WhetherContains = lsRelationPath.Contains(SourceMember);
                if (WhetherContains)
                {
                    return;
                }

                lsMemberID1.Clear();
                lsRelationPath.Add(lblHorizontalMember.Text);
               

                Find_Route(lblHorizontalMember.Text, DestinationMember);
            }


	    if(CheckTop(SourceMember))
	    {
		//code here....
	    }
}

推荐答案

只需要重新组织逻辑：

Just need to re-organise the logic:

if (CheckHorizontalSide(SourceMember))
  {
      bool WhetherContains = lsRelationPath.Contains(SourceMember);

      if (lblHorizontalMember.Text == DestinationMember)
      {

          lsRelationPath.Add(lblHorizontalMember.Text);
          lblRelationPath.Text = String.Join("-", lsRelationPath);
          lblRelationPath.Visible = true;
      }
      else if (!WhetherContains)
      {
           lsMemberID1.Clear();
           lsRelationPath.Add(lblHorizontalMember.Text);
          Find_Route(lblHorizontalMember.Text, DestinationMember);
      }

  }
