Namespace:  BCL
Assembly: xprbdn (in xprbdn.dll) Version: 45.01.02+1f9fd7ff9a8620394fec1839699751312debed40
Syntax
C# 
public int XPRBreadarrline(
	StreamReader fileStreamIn,
	int maxlen,
	string format,
	out int[] output,
	int numData
)
VB 
Public Function XPRBreadarrline ( 
	fileStreamIn As StreamReader,
	maxlen As Integer,
	format As String,
	<OutAttribute> ByRef output As Integer(),
	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   Int32
The out array, in this case if all requested objects were integers you could use this function, otherwise use the more general function that outputs an object[] object.
numData   Int32
The number of times to read the format string. For instance if the format string was "{i} , {i} ; {i} , " and the numdata=2 then the resultant format string to be read would be "{i} , {i} ; {i} , {i} , {i} ; {i}" as the method strips everything after the last occurence of "}".

Return Value

Int32
The integer number of items read, -1 on error.
Example
C# 
XPRBprob prob = new XPRBprob("NewProb");
FileStream file = new FileStream("FileReadInt.txt", FileMode.Open, FileAccess.Read);
fileStreamIn = new StreamReader(file);
outobjInt = new int[6];
prob.XPRBreadarrline(fileStreamIn, 200, "{i}, ", out outobjInt, 6);
fileStreamIn.Close();
file.Close();
