使用数据库值填充幻灯片演示文稿

Question

在我的应用程序中的某处，我需要创建幻灯片幻灯片并使用数据库值填充它。我可以使用本地模板创建幻灯片。但我不知道如何用DB值填充它。我搜索了网页，发现this，但它没有帮助我。没有图表或图表我想填充。这只是基于DB值的简单文本。
有人可以帮我吗？

下面的代码允许您创建一个新的幻灯片，选择它并将值添加到表中。你只需要现在阅读DB和填写好

int newaddslidecounter = 0; // checking how many new slides have to be inserted in order to split the table 
int startmultiplicator=1; // used in order to return current table row that must be pasted in new table 
int amountrowsshown =7; // amount of shown rows per table 
int fontsize = 12; 
// set position of new table/chart 
int topsize = 100; 
int leftsize = 100; 
int widthsize = 150; 
int heightsize = 150; 
Boolean alreadycreated = false; // checks if a table has already been created 
//Resizing all tables 
//and insert new Excel table instead while importing data from Excel table 
//used for visualization of data 
foreach (PowerPoint.Slide slide in presentation.Slides) 
      { 
       slide.Select(); 
       //loop through all shapes in slide 
       foreach (PowerPoint.Shape pptshape in slide.Shapes) 
       { 
        //Console.WriteLine("Shape type : " + pptshape.Type.ToString()); 
        //check if current shape is a table 
        //in order to do the manipulation 
        if (pptshape.Type.ToString().Equals("msoTable")) 
        { 
         for (int i = 1; i <= pptshape.Table.Rows.Count; i++)

代码源从数据库中读取数据 Reading values from SQL database in C#

using (SqlConnection connection = new SqlConnection(connectionString) 
using (SqlCommand command = new SqlCommand("select * from Requests where Complete = 0", connection)) 
{ 
    connection.Open(); 
    using (SqlDataReader reader = command.ExecuteReader()) 
    { 
     while (reader.Read()) 
     { 
      Console.WriteLine(reader["Username"].ToString()); 
      Console.WriteLine(reader["Item"].ToString()); 
      Console.WriteLine(reader["Amount"].ToString()); 
      Console.WriteLine(reader["Complete"].ToString()); 
     } 
    } 
} 

联接到一个数据库，例如可以在这里找到：

    thisConnection.Open(); 
    SqlCommand thisCommand = thisConnection.CreateCommand(); 
    thisCommand.CommandText = "SELECT CustomerID, CompanyName FROM Customers"; 
    SqlDataReader thisReader = thisCommand.ExecuteReader(); 
    while (thisReader.Read()) 
    { 
       Console.WriteLine("\t{0}\t{1}", thisReader["CustomerID"], thisReader["CompanyName"]);

    thisReader.Close(); 
    thisConnection.Close(); 
} 
catch (SqlException e) 
{ 
    Console.WriteLine(e.Message);
