举例说明:调用方法getList<int>(),数据本身是string类型,这样则需要将string类型数据类型转换成int类型,才能添加到List<int>集合中。 解决方法: 我们在命名空间System下,找到了Convert类下有一个ChangeType方法,它有三种重载方式,如下图所示: 关于这个方法的详细介绍请参照MSDN:http://technet.microsoft.com/zh-cn/l...

If A is a string array of any other size, then B is a cell array of character vectors that has the same size. If A has any other data type, then B is identical to A. If A is a string array, then convertStringsToChars converts any element that is: An empty string (displayed as...
The Convert String to Time method converts a string to time. It returns a variant of date variable type that represents a time in one of the following ranges: The time 0:00:00 through 23:59:59 The time 12:00:00 A.M. through 11:59:59 P.M. ...
string-name.c_str(); Copy At first, we use c_str() method to get all the characters of the string along with a terminating null character. Further, we declare an empty array of type char to store the result i.e. result of the conversion of string to char array. Finally, we use...
For a value of type DATE, the integer 32,767 represents the date September 17, 1992. Therefore, CONVERT returns NA when you attempt to convert any date later than this to a SHORTINTEGER value.Converting a Null StringWhen you convert a null string to a BYTE, you get a result of 32. ...
