在另一个函数中调用表单加载事件

Question

我需要关于如何调用我的代码中其他区域的表单加载以避免过度复制和粘贴的建议。在按下界面中的按钮后，我基本上需要在其他区域加载页面。我需要所有存在的代码，正如您可以看到它复制和粘贴多次一样。

public void FBinterface_Load(object sender, EventArgs e) 
{ 
    txtSerial.Focus(); 

    try 
    { 
     connection.Open(); 

     OleDbCommand command = new OleDbCommand(); 
     command.Connection = connection; 
     string SerialQuery = "select SerialNumber from Inventory"; 
     command.CommandText = SerialQuery; 

     //TO READ DATA 
     OleDbDataReader reader = command.ExecuteReader(); 
     while (reader.Read()) 
     { 
      comboSerial.Items.Add(reader["SerialNumber"]); 
     } 
     connection.Close(); 
    } 
    catch (OleDbException ex) 
    { 
     MessageBox.Show(ex.Message); 
     connection.Close(); 
    } 
    try 
    { 
     connection.Open(); 

     OleDbCommand command = new OleDbCommand(); 
     command.Connection = connection; 
     string PartQuery = "select PartNumber from Inventory"; 
     command.CommandText = PartQuery; 

     //TO READ DATA 
     OleDbDataReader reader = command.ExecuteReader(); 
     while (reader.Read()) 
     { 
      comboPart.Items.Add(reader["PartNumber"]); 
     } 
     connection.Close(); 
    } 
    catch (OleDbException ex) 
    { 
     MessageBox.Show(ex.Message); 
     connection.Close(); 
    } 
    try 
    { 
     connection.Open(); 

     OleDbCommand command = new OleDbCommand(); 
     command.Connection = connection; 
     string ROnumberQuery = "select ROnumber from Inventory"; 
     command.CommandText = ROnumberQuery; 

     //TO READ DATA 
     OleDbDataReader reader = command.ExecuteReader(); 
     while (reader.Read()) 
     { 
      comboRO.Items.Add(reader["ROnumber"]); 
     } 
     connection.Close(); 
    } 
    catch (OleDbException ex) 
    { 
     MessageBox.Show(ex.Message); 
     connection.Close(); 
    } 
    try 
    { 
     connection.Open(); 

     OleDbCommand command = new OleDbCommand(); 
     command.Connection = connection; 
     string LocationQuery = "select Location from Inventory"; 

     command.CommandText = LocationQuery; 

     //TO READ DATA 
     OleDbDataReader reader = command.ExecuteReader(); 
     while (reader.Read()) 
     { 
      comboLocation.Items.Add(reader["Location"]); 
     } 
     connection.Close(); 
    } 
    catch (OleDbException ex) 
    { 
     MessageBox.Show(ex.Message); 
     connection.Close(); 
    } 
} 

Answer 1

移动你的逻辑，以另一种方法，并调用它，当你想

public void FBinterface_Load(object sender, EventArgs e) 
{ 
    MyLogic(); 
} 

private void MyLogic() 
{ 
    txtSerial.Focus(); 
    try 
    { 
      //removed for brevity 
    } 
    catch (OleDbException ex) 
    { 
     MessageBox.Show(ex.Message); 
     connection.Close(); 
    } 
} 

现在称之为MyLogic方法时，你想要的。

例如：

public void button1_Click(object sender, EventArgs e) 
{ 
    //some code 

    MyLogic(); //calling the whole logic you want. 

    //extra code 
}

你尝试：

FBinterface_Load(this,null);
