int numData
)
Public Function XPRBreadarrline (
fileStreamIn As StreamReader,
maxlen As Integer,
format As String,
<OutAttribute> ByRef output As Object(),
numData As Integer
) As Integer
Parameters
- fileStreamIn StreamReader
- The open StreamReader to read the data from.
- maxlen Int32
- The maximum length of data to read.
- format String
- The format to read the data in. This is a string made up of the following
formats, seperated by any seperating characters. The format must be exact with
respect to spacing (if there are 0+ spaces between the entries then a space " "
must be included in the format string). See the BCL example programs for
examples of this.
- {g} – A double value.
- {i} – An integer value.
- {t} or {T} – A string value.
- {s} – A string within single quotes.
- {S} – A string within double quotes.
- output Object
- The out object array. The results from this must be unboxed to the
correct type on return and allocated to the relevant variables.
See the BCL examples for examples of this.
- numData Int32
- The number of times to read the format string. For instance
if the format string was "{i} , {g} ; {S} , " and the numdata=2
then the resultant format string to be read would be
"{i} , {g} ; {S} , {i} , {g} ; {S}" as the method strips everything
after the last occurence of "}".
Return Value
Int32The integer number of items read, -1 on error.
