Caml查詢按文件類型過濾

Question

以下查詢缺少什么？ 它從文檔庫中提取所有記錄嗎？

//Specify the Caml Query
            CamlQuery camlQuery = new CamlQuery();
            camlQuery.ViewXml = "<View Scope='Recursive'><Where><Contains><FieldRef Name='File_x0020_Type' /><Value Type='text'>msg</Value></Contains></Where></View>";

            ListItemCollection listItems = sharedDocumentsList.GetItems(camlQuery);

謝謝

您應該在“ View節點內部有一個“ Query View節點，並且在Where Query內部有“位置”：

camlQuery.ViewXml =
@"<View Scope='Recursive'>
  <Query>
    <Where>
      <Contains>
        <FieldRef Name='File_x0020_Type'/>
        <Value Type='text'>msg</Value>
      </Contains>
    </Where>
  </Query>
</View>";
