cqtk 你好

通过jit信息很难推断出是什么原因，你是在进行什么操作时出现该错误，能否发一个demo给我们调试一下。谢谢。

从我这边的调试结果来看，因为使用多线程导致在重绘控件时出错，我对代码进行了一点改动，主要是修改了TestError方法

namespace SpreadErrorDemo
{
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
BackgroundWorker backgroundWorker;
private delegate void InvokeCallback(BackgroundWorker backgroundWorker, DoWorkEventArgs e);
private void Form2_Load(object sender, EventArgs e)
{
this.fpSpread1.ActiveSheet.ColumnHeader.AutoText = HeaderAutoText.Numbers;
backgroundWorker = new BackgroundWorker();
backgroundWorker.DoWork += new DoWorkEventHandler(backgroundWorker_DoWork);
}
private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
this.TestError(worker, e);
}
private void button1_Click(object sender, EventArgs e)
{
backgroundWorker.RunWorkerAsync();
}
public void TestError(BackgroundWorker backgroundWorker, DoWorkEventArgs e)
{
if (this.InvokeRequired)
{
this.Invoke(new InvokeCallback(TestError), new object[] { backgroundWorker, e });
}
else
{
this.fpSpread1.ActiveSheet.ColumnHeader.Columns.Clear();
this.fpSpread1.ActiveSheet.ColumnHeader.Columns.Count = 10000;
this.fpSpread1.ActiveSheet.RowHeader.Rows.Clear();
this.fpSpread1.ActiveSheet.RowHeader.Rows.Count = 10000;
//还原列行数
this.fpSpread1.ActiveSheet.ColumnCount = 10000;
this.fpSpread1.ActiveSheet.RowCount = 10000;
int ttt = 0;
for (int i = 0; i < 1000000000; i++)
{
ttt++;
}
}
}
}
}
