本人小白，想实现将网页的表写入到word中并导出到本地。但是总是报错“System.NullReferenceException: 未将对象引用设置到对象的实例。
代码部分如下
protected void docWriteIn2(string TemplatePath)
{
Aspose.Words.Document Doc = new Aspose.Words.Document(TemplatePath); //载入模板
DocumentBuilder builder = new DocumentBuilder(Doc);
NodeCollection tables = Doc.GetChildNodes(NodeType.Table, true);
Aspose.Words.Tables.Table table1 = tables[0] as Aspose.Words.Tables.Table;
builder.MoveToBookmark("QInspectionDepartId");
builder.Write(QInspectionDepartId.Text.Trim());
builder.MoveToBookmark("Number");
builder.Write(Number.Text.Trim());
builder.MoveToBookmark("QQuantity");
builder.Write(QQuantity.Text.Trim());
builder.MoveToBookmark("QualifiedQuantity");
builder.Write(QualifiedQuantity.Text.Trim());
builder.MoveToBookmark("UqualifiedQuantity");
builder.Write(UqualifiedQuantity.Text.Trim());
builder.MoveToBookmark("PassRate");
builder.Write(PassRate.Text.Trim());
//拿到第一个表格：tableindex=0
Aspose.Words.Tables.Table table2 = tables[1] as Aspose.Words.Tables.Table;
//拿到第二行的row模板：rowindex=1
var roww = table2.Rows[1];
if (Session["receiptNumber"]!=null)
{
var TestInfo = Testinfo.findTestInfo(Session["receiptNumber"].ToString());
** QInspectionDepartId.Text = contextdb.S_Department_Info.Single(u => u.id == TestInfo.InspectionDepartId).DepartmentName;
** **//**这里肯定是有问题的**,问题出现在上面这一行****
// 第二行QInspectionDepartId.Text = contextdb.S_Department_Info.Single(u => u.id == DepartId).DepartmentName;
}
var TestBasicInfoList = db.GetTable<K_QCM_TestBasicInfo>();
var TargetListInfoList = db.GetTable<K_QCM_Target_List>();

if (value == 0)
{

//复制第2行
var row = roww.Clone(true);
//将复制的行插入当前行的上方
table2.Rows.Insert(1 + n, row);
//光标移动到：第一个表格的，第1行的第1列的格子里
builder.MoveToCell(1, n + 1, 0, 0);
//给序号填充内容
builder.Write((n + 1).ToString());
//给产品名称单元格填充内容
