如何在字符串中添加"0"填充,以便我的字符串长度始终为4？
例
If input "1", 3 padding is added = 0001
If input "25", 2 padding is added = 0025
If input "301", 1 padding is added = 0301
If input "4501", 0 padding is added = 4501
如何用前导零填充我的整数变量.就像我有一个值为20的整数abc,但我希望它是'0000020'.
码:
quarterlyReportDataCMMS.QRTrailerRecord.FileRecordCount = Convert.ToInt32(refEligibleClaimants.Count);
