问题描述

我正在尝试将字符串转换为日期，但是如何解决此问题会出现错误?

错误:从字符串"到类型日期"的转换无效.
该字符串采用dd/mm/yyyy格式，并且我使用了cdate和convert.todatetime函数，但在两种情况下转换均未成功完成.

I am trying to convert string to date but the error would occur how to solve this problem?

error : Conversion from string "" to type ''Date'' is not valid.
The string is in dd/mm/yyyy format and and I have used cdate and convert.todatetime functions but in both case conversion was not success-full.

推荐答案

DateTime.ParseExact("18-12-2007", "dd-MM-yyyy", CultureInfo.InvariantCulture)<br />

这是处理您使用的非标准日期格式所必需的.

This is needed to handle the date format you are using which is not a standard one.

<pre></pre>string datestring = "20000101";<br />
string date1 = DateTime.ParseExact(datestring, yyyyMMdd, null);<br />
// ... or ...<br />
DateTime dateResult;<br />
if (!DateTime.TryParseExact(datestring, yyyyMMdd,<br />
                            null, DateTimeStyles.AssumeLocal,<br />
                            out dateResult))<br />
    dateResult = DateTime.MinValue;
