本文介绍了如何将水晶报表绑定到手动创建的数据集的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我不想从代码中创建DataSet并将其设置为水晶报表的数据源.
如果不需要，我不想在 VS 中创建 DataSet xsd 文件.只是纯代码.

I wan't to create DataSet from code and set it as data source for crystal report.
I don't want to create a DataSet xsd file in VS if I don't have to. Just pure code.

DataSet ds = new DataSet();
DataTable tbl = new DataTable();
DataColumn cln = new DataColumn();
// I fill row, columns, table and add it to ds object
...

然后当我需要报告时，我会使用:

Then when I need report I use:

myReport.SetDataSource(ds);

这里的问题是我不知道如何绑定这个报告?如何添加字段?
我有一个文本和二进制数据(图像).

The problem here is I don't know how to bind this to report? How to add fields?
I have a text and binary data (image).

推荐答案

只有出路.正如罗萨多所建议的那样.一点点解释1. 创建一个 RPT 文件.2. 创建一个包含所需列的 XSD.3. 拖放 rpt 上的列.根据需要对其进行格式化.4. 现在创建连接，使用适配器填充该数据集.5.填充u数据集会自动填充报表列.

There is only way out. As suggested by rosado. Little bit explained 1. CReate a RPT File. 2. Create a XSD with the desired columns. 3. Drag drop the columns on the rpt. Format it as required. 4. Now create connection, use adapter to fill that dataset. 5. Filling u dataset will automatically fill the report columns.

下面是我的一个项目的示例代码.

Below is a sample code from one of mine project.

Invoice invoice = new Invoice(); // instance of my rpt file
var ds = new DsBilling();  // DsBilling is mine XSD
var table2 = ds.Vendor;
var adapter2 = new VendorTableAdapter();
adapter2.Fill(table2);                   

var table = ds.Bill;
var adapter = new BillTableAdapter();
string name = cboCustReport.Text;
int month = int.Parse(cboRptFromMonth.SelectedItem.ToString());
int year = int.Parse(cboReportFromYear.SelectedItem.ToString());
adapter.Fill(table, name,month,year);

ds.AcceptChanges();

invoice.SetDataSource(ds);
crystalReportViewer1.ReportSource = invoice;
crystalReportViewer1.RefreshReport();
