注意：我添加了实际的代码片段。只需滚动到结束。
// files is created by a OpenFileDialog.
public void Function(String[] files, ...)
{
for(int i; i<files.Length; i++)
{
WriteLine("File " + i + "/" + files.Length + " being processed.");
//... processing for a long time and printing information to console ...
}
//... print results, e.g.: "Results: bla bla"...
}
函数在另一个循环中调用。我运行了几次代码并认为它运行良好，直到我看到有一次它表现得很奇怪。我为上面的函数提供了一个数组长度为6的函数，预期的输出是这样的：
-------------------------
File 0/6 being processed.
...lots of output...
File 1/6 being processed.
...lots of output...
File 2/6 being processed.
...lots of output...
File 3/6 being processed.
...lots of output...
File 4/6 being processed.
...lots of output...
File 5/6 being processed.
...lots of output...
Results: bla bla...
-------------------------
但是，我得到的输出是这样的：
-------------------------
File 0/1 being processed.
...lots of output...
Results: bla bla...
File 0/3 being processed.
...lots of output...
File 1/3 being processed.
...lots of output...
File 2/3 being processed.
...lots of output...
Results: bla bla...
File 0/3 being processed.
...lots of output...
File 1/3 being processed.
...lots of output...
File 2/3 being processed.
...lots of output...
Results: bla bla...
File 0/6 being processed.
...lots of output...
File 1/6 being processed.
...lots of output...
File 2/6 being processed.
...lots of output...
File 3/6 being processed.
...lots of output...
-------------------------
当我看到该输出时，我在当前循环结束之前退出了执行（它运行了很长时间。）
看起来该函数工作正常（它运行 files.Length 次并在此之后输出结果。）但是，传递给函数的参数在某种程度上是错误的（有趣的是，该函数被多次调用。通常，它应该只运行在这种情况下一次。我的意思是，脚本文件中的行数决定了调用上述函数的次数，并且脚本文件只包含一行。）该参数（文件数组）来自 OpenFileDialog，这意味着我与它无关。我只是将数组传递给函数。
我仍在试图了解导致这种奇怪结果的原因。这种情况只发生过一次，但我仍然需要诊断问题；因为，我会让程序运行几天。它应该可以正常工作。
你对这种胡说八道有什么想法吗？
上述函数的实际代码：
public String Start(String[] files, StreamWriter reportWriter)
{
List<SortedDictionary<int, SortedDictionary<long, int>>>[] allResults
= new List<SortedDictionary<int,SortedDictionary<long,int>>>[files.Length];
List<SortedDictionary<int, SortedDictionary<long, int>>> results;
Simulation_DenemePositionEstimator p;
Simulation_WimaxStreamReader reader;
String ret;
for (int i = 0; i < files.Length; i++)
{
System.Console.WriteLine("File " + (i+1) + "/" + files.Length + " being processed.");
reader = new Simulation_WimaxStreamReader(grids, new StreamReader(files[i]));
p = new Simulation_DenemePositionEstimator(grids, reader);
// Using parameters in script file which were saved into
// different variables when Simulation instance was created.
results =
p.StartInvestigation(maxRssiDiff, maxCinrDiff, maxAvgTxPwrDiff,
maxUncontinuity, radiusForNeighbors, expansionFactor, increment,
n, numberOfIterations, resetCountForPositioning);
allResults[i] = results;
reader.Close();
}
ret = Statistics(allResults);
System.Console.WriteLine(ret);
reportWriter.WriteLine(ret);
reportWriter.Flush();
return ret;
}
调用函数代码：
// read a line from script file.
while((line = reader.ReadLine()) != null)
{
// line starting with # is comment.
if (line.StartsWith("#") == false)
{
// save parameters retrieved from script file into an array.
values = line.Split(delimiters);
// new Simulation instance with new parameters
sim = new Simulation(map, values);
// Start simulation. scenarioFiles comes from OpenFileDialog.
report = sim.Start(scenarioFiles, reportWriter);
//reportWriter.WriteLine(report);
reportWriter.WriteLine("---------------NEW-PARAMETERS---------------");
reportWriter.Flush();
}
}
