不能添加DLL引用？（后续） [英] Can't add DLL reference?(Follow up)

问题描述

跟进此
我也读过在其他一些问题上，但是我不明白会是什么会导致这种情况发生。权限？如何应用工作？什么是LAME？

我被定向到这个教程，并将它用于一个C＃程序，以执行按钮点击。

但是我在这行上收到错误

  [DllImport（ODBCCP32.dll）] 
  

说明

 无法找到类型或命名空间名称DllImport（您是否缺少使用目录或程序集引用？）
  

我已经尝试将该文件作为参考，但是我打了有这个错误

 请确保文件是可访问的，它是一个有效的程序集或COM组件
我缺少需要导入的东西吗？ 
这是我代码的一部分。
  using System; 
使用System.Runtime.InteropServices; 
 
命名空间DsnUtil {
 public partial class Form1：Form {
 [DllImport（ODBCCP32.dll）] 
 private static extern bool SQLConfigDataSource（// etc etc ）
 public Form1（）{
 button1_Click（）; 
} 
 
 private void button1_Click（object sender，EventArgs e）{
 // DoesWork 
} 
} 
  
 
 
解决方案
似乎我只是有一些困惑。 
我可以将.dll添加为资源而不是引用。 
我还分配了一个新的字符串资源作为dll的名称，以备稍后使用。
 
 
 
所有这一切都是有效的。 
 命名空间DSNUtility {
 
 public partial class Form1：Form {
 [DllImport（ odbccp32.dll）] 
 private static extern bool SQLConfigDataSource（IntPrt parent，int request，string driver，string attribute; 
 
 public form（）{
 InitializeComponent（）; 
} 
 
 //处理创建的方法（将在按钮上单击）
 public bool AddUserDSN（）{
 return SQLConfigDataSource（（IntPrt）0， 1，SQL Server，
DSN = Testing123\0Description = Testing123\0Network = blahblah\0Trusted_Connection = No\0Server = blahblahblah\0Database = XXXXXX\0）; 
 } 
 
 private void Form1_Load（object sender，EventArgs e）{
} 
 
 private void button1_Click（object sender，EventArgs e）{
 //调用添加用户方法
 AddUserDSN（）; 
} 
 } 
  
 
Follow up to This
I have also read up on some other questions but am not understanding what would cause this to happen. Permissions? How to apply a work around? Whats LAME?

I was directed to THIS tutorial and have worked it into a C# program to execute on Button Clicks.

However I get a error on this line
[DllImport("ODBCCP32.dll")]
stating
The type or namespace name "DllImport" could not be found (are you missing a using directory or an assembly reference?)
I have tried inporting that file as a reference but am then hit with this error
"Please make sure file is accessile, and that it is a valid assembly or COM component"
Am I missing something that I need imported? 
Here is a section of my code.
using System;
using System.Runtime.InteropServices;

namespace DsnUtil{
public partial class Form1 : Form{
[DllImport("ODBCCP32.dll")]
private static extern bool SQLConfigDataSource(//etc etc)
public Form1(){
   button1_Click();
}

private void button1_Click(object sender, EventArgs e){
   //DoesWork
}
}

解决方案
It seemed that I just had some things confused.
I was able to add the .dll as a Resource instead of a reference.
I also assigned a new string resource as the name of the dll in case I would like to use it later.

All in all this is what worked.
namespace DSNUtility{

public partial class Form1 : Form{
[DllImport("odbccp32.dll")]
private static extern bool SQLConfigDataSource(IntPrt parent, int request, string driver, string attribute;

public form(){
InitializeComponent();
}

//Method to handle the creation(Will be called on a Button Click)
public bool AddUserDSN(){
return SQLConfigDataSource((IntPrt)0, 1, "SQL Server",
"DSN=Testing123\0Description=Testing123\0Network=blahblah\0Trusted_Connection=No\0Server=blahblahblah\0Database=XXXXXX\0");
}

private void Form1_Load(object sender, EventArgs e){
    }

private void button1_Click(object sender, EventArgs e){
//Call the Add User Method   
AddUserDSN();
}   
}
