我正在开发一个针对 Windows 商店的 LOB 应用程序，我想知道为它创建自定义报告的选项有哪些。除了打印之外，用户可能还希望导出为 PDF 或 CSV。
我不知道 Windows 商店应用程序有哪些 API。谷歌搜索没有多大帮助。
如果没有任何工具可以创建报告，你们会建议什么？
查看 Microsoft 的PrintSample，它会打印网格组件的内容。我怀疑在这种情况下如何设置页面大小，以便我可以正确格式化报告。
非常感谢任何帮助/想法。
谢谢！

不幸的是，现在没有用于生成 PDF/Excel 报告的免费库（工具/sdk）Windows Store App。
但是，如果您有钱购买 - 检查PDFTron 和Syncfusion

我已向客户承诺为他们的 RT 平板电脑构建一个 Windows 应用商店应用程序。我不知道当时的技术是如此……有限。例如，没有缺少 System.Data、StreamWriter 和许多其他常见的业务应用程序功能……对我来说最令人惊讶的是构建报告的标准方法。到目前为止，它们似乎还没有集成 SSRS（希望很快就会到来？）。看看 Crystal Reports，他们目前没有扩展到 Windows RT 平台的计划。
微软的 Print 样本也没有给我留下深刻的印象，这似乎比什么都好。所以我创建了一个更适合我需要的方法。我相信你们中的许多人都想出了自己的方法，包括购买第三方工具，但就我而言，我通过 HTML 和当前 WindowsRT 可用的 SQLite 方法生成了我的自定义报告（我多么想念 System.Data！）。如前所述，StreamWriter 在 Windows RT 上似乎不太合理，所以我对替代方案做了一些研究，这对我有用：
private async void PrintEstimate()
{
// BUILD ESTIMATE WHICH IS AN HTML PAGE BECAUSE THEIR DID NOT APPEAR TO BE
// A WAY TO REALLY BUILD REPORTS FOR WINRT APPLICATIONS AT THIS POINT WITHOUT
// PURCHASING THRIRD PARTY TOOLS.
// Validate Estimate
// Are their values in the estimate list?
if (this.listServices.Items.Count < 1)
{
MessageDialog msgDialog = new MessageDialog("You must first add services before you can print an estimate.");
// Show the message dialog
await msgDialog.ShowAsync();
return;
}
if (string.IsNullOrEmpty(this.txtTotal1.Text))
{
MessageDialog msgDialog = new MessageDialog("You must first add the total before you can print an estimate.");
// Show the message dialog
await msgDialog.ShowAsync();
return;
}
var strAppPath = Path.Combine(Windows.ApplicationModel.Package.Current.InstalledLocation.Path, @"EstimateReport\NewAPEMiniLogo.png");
var dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "APE.db");
// ESTIMATE VARIABLES
string dtDateOfEstimate = Convert.ToString(this.dateEstimate.Date.ToString("MM/dd/yyyy"));
string strCustomerName = null;
string strCustomerAddress = null;
string strCustomerPhone = null;
string strCustomerNotes = null;
double totalCost = Convert.ToDouble(this.txtTotal1.Text);
double taxes = .08 * totalCost;
string strEstimateNote = this.txtNotes.Text;
string base64;
// THE WINRT Environment is very limited as far as accessing local resources... and from all that I have found
// Is purposely limited in allowing this to be done... thus here I am converting the image to a base64 string
//StorageFolder appFolder = ApplicationData.Current.LocalFolder;
StorageFolder appFolder = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFolderAsync("EstimateReport");
StorageFile imageFile = await appFolder.GetFileAsync("NewAPEMiniLogo.png");
using (var stream = await imageFile.OpenAsync(FileAccessMode.Read))
{
var reader = new DataReader(stream.GetInputStreamAt(0));
var bytes = new byte[stream.Size];
await reader.LoadAsync((uint)stream.Size);
reader.ReadBytes(bytes);
base64 = Convert.ToBase64String(bytes);
}
// IF NEW ESTIMATE
if (currentEstimateID == 0)
{
// CREATE/ INSERT NEW ESTIMATE
using (var db = new SQLite.SQLiteConnection(dbPath))
{
db.CreateTable<APE_Painting_App.DataAccess.Estimate>();
db.RunInTransaction(() => { db.Insert(new DataAccess.Estimate() { CustomerID = currentCustomerID, EstimateDate = Convert.ToDateTime(dtDateOfEstimate), TotalCost = totalCost, EstimateNotes = strEstimateNote }); });
string sql = "SELECT last_insert_rowid()";
currentEstimateID = db.ExecuteScalar<int>(sql);
db.Close();
}
}
else
{
// ELSE UPDATE CURRENT ESTIMATE
dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "APE.db");
using (var db = new SQLite.SQLiteConnection(dbPath))
{
// THE ONLY THREE ITEMS THAT SHOULD BE CHANGEABLE AT THE ESTIMATE LEVEL ARE TOTAL COST, ESTIMATE NOTES AND ESTIMATE DATE.
var objEstimate = db.Table<Estimate>().Where(c => c.EstimateID == currentEstimateID).Single();
objEstimate.EstimateDate = Convert.ToDateTime(dtDateOfEstimate);
objEstimate.TotalCost = totalCost;
objEstimate.EstimateNotes = strEstimateNote;
objEstimate.JobAwarded = this.chkJobAwarded.IsChecked.Value;
db.Update(objEstimate);
db.Close();
}
}
// GET CUSTOMER VALUES
using (var db = new SQLite.SQLiteConnection(dbPath))
{
var objCustomer = db.Table<Customer>().Where(c => c.CustomerID == currentCustomerID).Single();
strCustomerName = objCustomer.FirstName + " " + objCustomer.LastName;
strCustomerAddress = objCustomer.Address1 + " " + objCustomer.Address2 + " " + objCustomer.City + " " + objCustomer.State + " " + objCustomer.Zip;
strCustomerPhone = objCustomer.Phone1;
strCustomerNotes = objCustomer.CustomerNote;
db.Close();
