林下面的代碼：SharePoint 2010列表上的CAML查詢？
string xpathresultBTADSLMAX = "BT/Max Standard";
if (xpathresult2 == "BT ADSL Max")
{
//Creating the CAML query to perfomr the query on the list to find the required values
SPQuery query = new SPQuery();
//try to find items in this list that matches the result of the XPATH query performed
earlier
//in this case "BT/Standard"
string camlquery = @"<Query>
<Where>
<Eq>
<FieldRef Name='Vendor_x0020_Product_x0020_Name'/>
<Value Type='Text'>" + xpathresultBTADSLMAX + @"</Value>
</Eq>
</Where>
</Query>";
query.Query = camlquery;
query.ViewFields = "<FieldRef Name='Fabric_x0020_Name'/><FieldRef
Name='Defined_x0020_For/><FieldRef name='MPLS'/>"; //selecting only the required
fields
from the CAML query
SPListItemCollection listItemCollection = list.GetItems(query);
//string fabricName = (string)item["Fabric_x0020_Name"]; commented out temporarily
//string definedFor = (string)item["Defined_x0020_For"]; commented out temporarily
string fabricName = (string)item["Fabric_x0020_Name"];
string definedFor = (string)item["Defined_x0020_For"];
AvailabilityCheckerResultsTwo.Controls.Add(new LiteralControl(fabricName, definedFor
));
}
在上面的代碼中，我想顯示從具有「BT /最高標準」的供應商Produc名稱列表項目的具體信息。我想要顯示的值是「Fabric Name」和「Defined For」。
然後，我希望能夠通過添加一個文字控件，但它根本不工作，以顯示他們在asp佔位符。有什麼我在這裏做錯了嗎？請提供一些關於如何實現這一目標的建議。
許多Thans提前！
更新！
因此我對代碼進行了一些更改，這些代碼基本解決了前面提到的問題。我現在可以在asp佔位符中顯示CAML查詢的結果。
string xpathresultBTADSLMAX = "BT/Max Standard";
//Executing the correct query based on a if condition for BT ADSL
if (xpathresult2 == "BT ADSL Max")
{
//Creating the CAML query to perfomr the query on the list to find the required values
SPQuery query = new SPQuery();
//try to find items in this list that matches the result of the XPATH query performed
earlier
//in this case "BT/Standard"
string camlquery = @"<Query>
<Where>
<Eq>
<FieldRef Name='Vendor_x0020_Product_x0020_Name'/>
<Value Type='Text'>" + xpathresultBTADSLMAX + @"</Value>
</Eq>
</Where>
</Query>";
query.Query = camlquery;
//query.ViewFields = "<FieldRef Name='Fabric_x0020_Name'/><FieldRef
Name='Defined_x0020_For'/><FieldRef name='MPLS'/>"; //selecting only the required
fields from the CAML query, GIVES ERROR
SPListItemCollection listItemCollection = list.GetItems(query);
//string fabricName = (string)item["Fabric_x0020_Name"]; commented out temporarily
//string definedFor = (string)item["Defined_x0020_For"];
//string feniedFor = (string)item["Defined_x0020_For"];
//AvailabilityCheckerResults3.Controls.Add(new LiteralControl(fabricName + " " +
definedFor));
//AvailabilityCheckerResultsTwo.Controls.Add(new LiteralControl(fabricName));
commented out temporarily
//string fabricName = (string)listItemCollection["Fabric_x0020_Name"].ToString;
/*string fabricName = listItemCollection.ToString();
AvailabilityCheckerResultsTwo.Controls.Add(new LiteralControl(fabricName));*/
foreach (SPListItem item in listItemCollection)
{
try
{
string results56 = (string)item["Fabric_x0020_Name"] + " " +
(string)item["Defined_x0020_For"] + " " + "<b>MPLS:</b> " + (string)item["MPLS"] +
"<br/>" + "<br/>";
AvailabilityCheckerResultsTwo.Controls.Add(new LiteralControl(results56));
}
catch (Exception err)
{
AvailabilityCheckerResultsTwo.Controls.Add(new LiteralControl(err.ToString()));
}
}
}
但是，我現在有另一個問題，我得到列表中的所有反饋，這不是預期的結果。下面是輸出：
羊駝 的一個骯髒的ADSL產品：CCTV第三方遠程訪問互動模式和網站測試 MPLS：沒有
地榆 家庭用戶& SOHO產品（< 5用戶網站）可以支持< 5個併發呼叫的VoIP連接。 IPT包 MPLS：是
CAML查詢應該只顯示「羊駝」的結果。我怎樣才能得到所需的項目，而不是列表中的所有項目？它可能是我做錯了！
非常感謝
我使用標籤的原因是因爲我希望查詢帶回完整的結果。然後我使用（query.ViewFields =「

是的，我得到的結果！ –
