Question

<mat-dialog-content> <form [formGroup]="carForm" novalidate> <mat-form-field class="example-chip-list"> <mat-chip-list #chipList> <mat-chip *ngFor="let car of cars" [selectable]="selectable" [removable]="removable" (removed)="remove(car)"> {{car.name}} <mat-icon matChipRemove *ngIf="removable">cancel</mat-icon> </mat-chip> <input matInput formControlName="cars" placeholder="New car..." [matChipInputFor]="chipList" [matChipInputSeparatorKeyCodes]="separatorKeysCodes" [matChipInputAddOnBlur]="addOnBlur" (matChipInputTokenEnd)="add($event)" required> </mat-chip-list> </mat-form-field> </form> </mat-dialog-content> <mat-dialog-actions> <button mat-raised-button [mat-dialog-close]="carForm.value" tabindex="1" [disabled]="!carForm.valid" color="primary">Save</button> <button mat-button [mat-dialog-close]="null" tabindex="-1">Cancel</button> </mat-dialog-actions>是路径，即directory，可能包含也可能不包含名为L:\\H435431 Project Name或2-Storage的子目录。如果发现了该目录，我想获取其子目录的列表并进行测试以查看其是否包含2-STORAGE。

当我逐步执行此代码时，! Issued Packages返回期望的文件夹数组，并且subdirectories已正确设置为containsStorage。反过来，true可以正确反映我接下来要搜索的目录名称d。 L:\\H435431 Project Name\\2-Storage永远不会被分配ad的值，并且永远不会搜索目录。为什么会这样？

Directory.GetDirectories(d)

Answer 1

检查SubSubDirectories对我们是否为空，如果其中没有内容，则没有任何内容可以迭代。

   string[] subirectories = Directory.GetDirectories(directory);
                foreach (string d in subirectories)
                {
                    if (Regex.IsMatch(d, @"2-Storage", RegexOptions.IgnoreCase))
                    {
                        containsStorage = true;
                        string[] subSubDirectories = Directory.GetDirectories(d);
                        foreach (string ad in subSubDirectories)
                        {
                            if (Regex.IsMatch(ad, @"! Issued Packages", RegexOptions.IgnoreCase))
                            {
                                containsIssued = true;
                            }
                        }
                    } 
                }
