用存储过程中的数据填充组合框

Question

我想在我的存储过程中用名称填充我的组合框。

public frmAddEdit(Book book, Author author) 
    { 
     _book = book; 
     _author = author; 
     _dataAccess = DataAccess.GetInstance; 
     _dataAccess.SetConnectionString(_dataAccess.GetServerConnectionString()); 
     ComboFill(); 
     InitializeComponent(); 
    } 

这是我的负荷形式

public void AddEditBook_Load(object sender, EventArgs e) 
    { 

     txtTitle.Text = _book.Title; 
     //comboBox1.DataSource = _book.FullName; 
     //comboBox1.ValueMember = "AuthorId"; 
     //comboBox1.DisplayMember = "FullName"; 
     ComboFill(); 
     //txtAuthor.Text = _author.FullName; 
     //txtAdd.Text = book.Title; 
    } 

我的组合框

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) 
    { 
     DataRowView view = comboBox1.SelectedItem as DataRowView; 
     string fullName = view["FullName"].ToString(); 


    } 

东西，我在网上看到试了一下。

  public void ComboFill() 
    { 
     DataRow dr; 
     DataTable dt = new DataTable(); 

     dr = dt.NewRow(); 
     // dr.ItemArray = new object[] { 0, "Select Author" }; 
     dt.Rows.InsertAt(dr, 0); 
     comboBox1.DataSource = _book.FullName; 
     comboBox1.ValueMember = "AuthorId"; 
     comboBox1.DisplayMember = "FullName"; 
    } 

Answer 1

//assume this that you have datatable filled from stored procedure 
//This is sample for populating your combo 
DataTable dt = new DataTable(); 
dt.Columns.Add("AuthorID", typeof(int)); 
dt.Columns.Add("FullName", typeof(string)); 

DataRow dr = null; 
for (int i = 0; i < 10; i++) 
{ 
    dr = dt.NewRow(); 
    dr[0] = i; 
    dr[1] = "ABC" + i + 2 * i; 

    dt.Rows.Add(dr); 
} 

comboBox1.DataSource = dt; // this will be populated from SP 
comboBox1.ValueMember = "AuthorID"; 
comboBox1.DisplayMember = "FullName"; 

Answer 2

comboBox1.DataSource = _bool.FullName;是错误的。它应该是：

comboBox1.DataSource = _book;
