下面的代码给了我下面的错误。我想我需要 "InvokeRequired" 。但我不明白我该如何使用?
错误:跨线程操作无效:控件“statusBar1”从创建它的线程以外的线程访问。
编码 :
public void CalculateGeneration(int nPopulation, int nGeneration)
{
int _previousFitness = 0;
Population TestPopulation = new Population();
for (int i = 0; i < nGeneration; i++)
{
if (_threadFlag)
break;
TestPopulation.NextGeneration();
Genome g = TestPopulation.GetHighestScoreGenome();
if (i % 100 == 0)
{
Console.WriteLine("Generation #{0}", i);
if ( ToPercent(g.CurrentFitness) != _previousFitness)
{
Console.WriteLine(g.ToString());
_gene = g;
statusBar1.Text = String.Format("Current Fitness = {0}", g.CurrentFitness.ToString("0.00"));
this.Text = String.Format("Sudoko Grid - Generation {0}", i);
Invalidate();
_previousFitness = ToPercent(g.CurrentFitness);
}
if (g.CurrentFitness > .9999)
{
Console.WriteLine("Final Solution at Generation {0}", i);
statusBar1.Text = "Finished";
Console.WriteLine(g.ToString());
break;
}
}
}
}
