比较两个list<string>是否相等

完全一致的话遍历equal就可以 但是元素一致排序不一致呢

想法1 先排序再遍历一致 list的排序blog.csdn.net/jimo_lonely… 排序然后再Enumerable.SequenceEqual

                    List<string> codeLabelsBefore = new List<string>();
                    foreach (var codeSection in sectionControl.CodeSections)
                    {
                        codeLabelsAfter.Add(codeSection.CodeSectionLabel);
                    }
                    foreach (var codeSection in mOriginCodeSection)
                    {
                        codeLabelsBefore.Add(codeSection.CodeSectionLabel);
                    }
                    if ((codeLabelsAfter.Count == 0) && (codeLabelsBefore.Count == 0))
                    {
                        this.mCodeSectionIsChanged = false;
                    }
                    else
                    {
                        codeLabelsAfter.Sort();
                        codeLabelsBefore.Sort();
                        if(Enumerable.SequenceEqual(codeLabelsAfter, codeLabelsBefore))
                        {
                            this.mCodeSectionIsChanged = false;
                        }
                        else
                        {
                            this.mCodeSectionIsChanged = true;
                        }
                    }
