DataGridView中的最大行数

问题描述

当count很大时，以下语句抛出Out of Memory异常（我看到这个为count = 44百万）（注意我使用虚拟模式只填充可见单元格）

dataGrid .RowCount = count;

我想修改如下：

试试{
dataGrid.RowCount = count;
} catch（OutOfMemoryException） {

//将计数设置为合理的值
count = rational_value;

ShowMessage（"仅显示{0}行"，计数）;
dataGrid.RowCount = count;






我的问题是：这里合理的行数是多少。 datagridview的文档并没有将任何最大值放在数据网格可以拥有的行数上，但实际上存在内存限制。解决这个问题的最佳方法是什么？

The following statement throws an Out of Memory exception when count is large (I saw this for count = 44 million) (Note that I am using virtual mode to populate only the visible cells)

dataGrid.RowCount = count;

I want to modify this as follows :

try {
    dataGrid.RowCount = count;
} catch (OutOfMemoryException){

    // set count to reasonable value
    count = reasonable_value;

    ShowMessage ("Showing only {0} rows", count);
    dataGrid.RowCount = count;

}


My question is : What is a reasonable row count here. The documentation for datagridview doesnt put any max value on the row count a datagrid can have, but in practice there is a memory limitation. What is the best way to work around this problem
