Question

每个文档（inputStream IS）都有一个名为生效日期的字段。我需要将所有这些单独的文档合并为一个按生效日期排序的文档。

import java.util.Properties;
import java.io.InputStream;

for( int i = 0; i < dataContext.getDataCount(); i++ ) {
  InputStream is = dataContext.getStream(i);
  Properties props = dataContext.getProperties(i);
  dataContext.storeStream(is, props);
}

由于纳格

将您的文档添加到private void Form1_Options_Load(object sender, EventArgs e) { String connectionString; connectionString = ConfigurationManager.ConnectionStrings["myConnectionString"].ConnectionString; conn = new SqlConnection(connectionString); String Sequel = "SELECT id,ProductName,ModelType FROM Product"; SqlDataAdapter da = new SqlDataAdapter(Sequel, conn); DataTable dt = new DataTable(); conn.Open(); da.Fill(dt); foreach (DataRow dr in dt.Rows) { parentNode = treeView1.Nodes.Add(dr["ProductName"].ToString()); //treeView1.Nodes.Add(dr["ModelType"].ToString()); PopulateTreeView(Convert.ToInt32(dr["Id"].ToString()), parentNode); } } public void PopulateTreeView(int parentId, TreeNode parentNode) { String Seqchildc = "Select * From Model WHERE ProductId = "+ parentId + ""; SqlDataAdapter dachildmnuc = new SqlDataAdapter(Seqchildc, conn); DataTable dtchildc = new DataTable(); dachildmnuc.Fill(dtchildc); TreeNode childNode; foreach (DataRow dr in dtchildc.Rows) { if (parentNode == null) childNode = treeView1.Nodes.Add(dr["ModelName"].ToString()); //childNode.Nodes.Add(dr["ModelType"].ToString()); else childNode = parentNode.Nodes.Add(dr["ModelName"].ToString()); //PopulateTreeView(Convert.ToInt32(dr["Id"].ToString()), childNode); } treeView1.ExpandAll(); //Connect(); }，然后使用ArrayList和比较日期的比较器。之后，使用for-each循环遍历List.sort(Comparator)并将文档添加到输出中。
