Syntax
public int XPRBreadarrline(
	StreamReader fileStreamIn,
	int maxlen,
	string format,
	out Object[] output,
	int numData
)

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

Int32
The integer number of items read, -1 on error.
