//自动调整ListView的列宽的方法
public void AutoResizeColumnWidth(ListView lv)
{
int count = lv.Columns.Count;

Graphics graphics = lv.CreateGraphics();
int width;
lv.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);
for (int i = 0; i < count; i++)
{
string str = lv.Columns[i].Text;
MaxWidth = lv.Columns[i].Width;

foreach (ListViewItem item in lv.Items)
{
str = item.SubItems[i].Text;
width = (int)graphics.MeasureString(str, lv.Font).Width;
if (width > MaxWidth)
{
MaxWidth = width;
}
}
if (MaxWidth <= 150)
{
lv.Columns[i].Width = MaxWidth;
}
else
