打印ListView控件的内容，打印DataGird控件的内容有现成开源的
www.webmis.com.cn只要是二维的，全部可以打印打印ListView，只需将ListView转换为二维数组。
public string[,] ToStringArray(ListView listView,bool includeColumnText)
{
ListView lvw = listView;
int rowsCount = lvw.Items.Count;
int colsCount = lvw.Columns.Count; //包括列标题
if (includeColumnText)
{
rowsCount++;
} string[,] arrReturn = null;

arrReturn = new string[rowsCount,colsCount]; int i = 0; if (includeColumnText)
{
//写标题
for(i = 0 ; i < colsCount; i++)
{
arrReturn[0,i] = lvw.Columns[i].Text;
} i = 1;
} //写数据行Items
int rowIndex = 0;
for(; i < rowsCount; i++,rowIndex++)
{
for (int j = 0; j < colsCount; j++)
{
arrReturn[i,j] = lvw.Items[rowIndex].SubItems[j].Text;
}
} return arrReturn;
}
