也可以用捕捉错误的方法:

private string GetDateString(string pVal, string dateFormat)
{
string dtFLong = dateFormat;
string dtFShort = dateFormat.Replace("MM", "M").Replace("dd", "d");
string[] expectedFormats = new string[] {dtFLong, dtFLong.Replace("-", "/"), dtFLong.Replace("-", "."), dtFShort, dtFShort.Replace("-", "/"), dtFShort.Replace("-", ".")};
System.IFormatProvider format = new System.Globalization.DateTimeFormatInfo();

try
{
string strReturn = DateTime.ParseExact(pVal, expectedFormats, format, System.Globalization.DateTimeStyles.AllowWhiteSpaces).ToString("MM-dd-yyyy");
return strReturn;
}
catch(Exception exp)
{
throw(exp);
}
}

有个简单的，用Like

If str Like "[1,2]###-[0,1]#-##" Then
