ListView无外乎也是一个二维形式的,下面提供一个把ListView转换为二维数组。
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;
}
打印ListView:
private void btnPrintEasy_Click(object sender,System.EventArgs e)
{
MisGoldPrinter webmis = new MisGoldPrinter();//打印组件
webmis.Title = "MIS金质打印通/nWWW.WebMIS.COM.CN";//网格标题
webmis.DataSource = ToStringArray(listView,true);//任意二维的数据通通打印
webmis.Preview();//打印预览
}
VB.Net:
Private Sub btnPrintEasy_Click(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles btnPrintEasy.Click
Dim webmis As MisGoldPrinter'打印组件
webmis = New MisGoldPrinter
webmis.Title = "MIS金质打印通"+vbCrLf+"WWW.WebMIS.COM.CN"'网格标题 webmis.DataSource = ToStringArray(listView,true)'任意二维的数据通通打印 webmis.Preview() '打印预览End Sub
