Return Value
Type: System::String^If successful, a substring of the formatted String, which includes literals, prompts, and optionally password characters; otherwise the Empty string.
This version of the overloaded ToString method returns a substring of the formatted string, starting at the position startPos and including the subsequent number of characters specified by the length parameter. The returned string includes prompts and literals according to the current values of the IncludePrompt and IncludeLiterals properties, respectively. If the ignorePasswordChar parameter is true, it will return the original input characters, ignoring the value of the PasswordChar property. If this parameter is false, it will use the password character to obscure editable user input if the PasswordChar property is set to a value other than null.
Important |
|---|
Because this method potentially reveals information that is usually protected in the user interface by password characters, it should be used with extreme caution to avoid accidentally revealing sensitive user data. |
ToString performs the following actions when there are discrepancies in the input parameters:
If startPos is less than zero, the starting position is set to zero.
If startPos is greater than or equal to the actual Length of the formatted string, the Empty string is returned.
If length is greater than the remaining number of characters past the starting position, only the remaining characters are returned.
If length is less than or equal to zero, the Empty string is returned.
