在 C# 中将字符串转换为 DateTime
I am trying to convert a string in the format "20110617111051" to date time. Currently I am using String.SubString() function to extract year, month, day, time to format a standard string and then using Convert.ToDateTime(string). Is there any other simple way to do this?
我正在尝试将格式为“20110617111051”的字符串转换为日期时间。目前我正在使用 String.SubString() 函数来提取年、月、日、时间来格式化标准字符串，然后使用 Convert.ToDateTime(string)。有没有其他简单的方法可以做到这一点？
Dim x as String="20110617110715"
Dim standard as string = x.SubString(0,4) & "-" & x.SubString(4,2) & "-" & x.SubString(6,2) 'and time
Dim dateTime as DateTime = Convert.ToDateTime(standard)

You can use DateTime.ParseExact.
您可以使用DateTime.ParseExact.
DateTime date = DateTime.ParseExact(x, "yyyyMMddHHmmss", CultureInfo.CurrentCulture);

Use the DateTime.ParseExactfunction in conjunction with the exact format of your input string. Example:
将该DateTime.ParseExact函数与输入字符串的确切格式结合使用。例子：
C#:
C＃：
string input = "20110617111051";
string format = "yyyyMMddhhmmss";
DateTime dateTime = DateTime.ParseExact(input, format, CultureInfo.InvariantCulture);
VB:
VB：
Dim input As String = "20110617111051"
Dim format As String = "yyyyMMddhhmmss"
Dim dateTime as DateTime = DateTime.ParseExact(input, format, CultureInfo.CurrentCulture)
