开关不输入大小写但值匹配

Switch not entering cases but values match

我对下面的代码有疑问。我有一个 switch 语句,它没有进入它的任何情况。假设 propType 的值为 "ID",开关应将其与大小写 "id" 相匹配,但它没有这样做。我做错了什么?

case "button":
                        Button ctrlButton = new Button();
                        for (int j = 0; j < ctrlProperties.Length; j++)
                        {
                            string currentProperty = ctrlProperties[j];
                            int propDelimiterPos = currentProperty.IndexOf(propDelimiter);
                            string propType = currentProperty.Substring(0, propDelimiterPos);
                            string propValue = currentProperty.Substring(propDelimiterPos + 2);
                            switch (propType.ToLower())
                            {   
                                #region PROPERTY PARAMETERS LEVEL
                                case "text":
                                    ctrlButton.Text = propValue;
                                    break;
                                case "font":
                                    int fontDelimiterPos = propValue.IndexOf(pntDelimiter);
                                    string fontName = propValue.Substring(0, fontDelimiterPos);
                                    string fntSize = propValue.Substring(fontDelimiterPos + 1);
                                    int fontSize = int.Parse(fntSize);
                                    ctrlButton.Font = new Font(fontName, fontSize);
                                    break;
                                case "bounds":
                                    string[] boundsValues = propValue.Split(pntDelimiter);
                                    Rectangle bounds = new Rectangle(
                                                            new Point(Convert.ToInt32(boundsValues[0]), Convert.ToInt32(boundsValues[1])),
                                                            new Size(Convert.ToInt32(boundsValues[2]), Convert.ToInt32(boundsValues[3])));
                                    ctrlButton.Bounds = bounds;
                                    break;
                                case "id":
                                    ctrlButton.Name = propValue;
                                    break;
                                #endregion
                            }
                            this.Controls.Add(ctrlButton);
                            ctrlButton.Show();
                        }
                        break;

这可能是由于您的字符串中有额外的 space 试试这个 propType.Trim().ToLower()
