Array.Sort可以实现便捷的字典排序,但如果完全相信他,那么就容易产生些异常!太顺利了,往往是前面有坑等你。
比如:微信接口,好多地方需要签名认证,签名的时候需要用的字典排序,如果只用Array.Sort()会出现签名异常的情况,而且是偶尔出现。
问题就在于他的排序默认没有区分大小写,这跟微信的签名将不匹配,所以还是需要自己实现比较的方法
public class DictionarySort : System.Collections.IComparer { public int Compare(object oLeft, object oRight) { string sLeft = oLeft as string; string sRight = oRight as string; int iLeftLength = sLeft.Length; int iRightLength = sRight.Length; int index = 0; while (index < iLeftLength && index < iRightLength) { if (sLeft[index] < sRight[index]) return -1; else if (sLeft[index] > sRight[index]) return 1; else index++; } return iLeftLength - iRightLength; } } string[] arr = { "E0o2-at6NcC2OsJiQTlwlCYXETNlXymc-tIaxXdRNahmhLtvORQGZfIvXWmiTberoB4ARrwHR-XxB47vfIKY_Q", "1449221063", "p8hR6s3Eljz2TLLJab7rmJaOXHvc", "a9233845d1c74e8194e6979a4210c804" }; Array.Sort(arr); string tmpStr = string.Join("", arr); this.textBox1.Text = tmpStr; //1449221063a9233845d1c74e8194e6979a4210c804E0o2-at6NcC2OsJiQTlwlCYXETNlXymc-tIaxXdRNahmhLtvORQGZfIvXWmiTberoB4ARrwHR-XxB47vfIKY_Qp8hR6s3Eljz2TLLJab7rmJaOXHvc Array.Sort(arr, new DictionarySort()); this.textBox2.Text = string.Join("", arr); //1449221063E0o2-at6NcC2OsJiQTlwlCYXETNlXymc-tIaxXdRNahmhLtvORQGZfIvXWmiTberoB4ARrwHR-XxB47vfIKY_Qa9233845d1c74e8194e6979a4210c804p8hR6s3Eljz2TLLJab7rmJaOXHvc
