l 注意python与c# format函数的不同 C# :string str9 =string.Format("{0:F2}",56789); //result: 56789.00 Python: string str9 =”{0:.2f}”.format(56789); 2.Console.WriteLine() 与format类似 其中隐含了string.format方法 1. 2. 3. 4. 5. 6. 7. Python 数据转换 l int() 与C#中convert...

据我所知,我们想从左边填充0,使zip至少有5个数字。如果你的情况那么 private static string GetZip(string value) => string.IsNullOrEmpty(value) ? new string('0', 5) : value.PadLeft(5, '0'); usage: public string SomeMethod(string originalZip) { string zip = GetZip(originalZip); ...}...
