c＃二次开发消息扑捉写入数据库失败
1）在调试的时候，是可以通过的；在客户机上，到写入数据库的时候就崩溃了；没任何提示，窗口一闪而过，没了；2）
代码如下：
#region BT Dll

public static extern bool InitializationBTDriver(GetTelID x, int y, int z);
[DllImport("BT.dll", EntryPoint = "InitializationMsg")]
public static extern bool InitializationMsg(int hwd);
[DllImport("BT.dll", EntryPoint = "ExitBTDriver")]
public static extern bool ExitBTDriver();
[DllImport("BT.dll", EntryPoint = "GetCall")]
public static extern bool GetCall(StringBuilder i);
[DllImport("BT.dll", EntryPoint = "GetConnect")]
public static extern bool GetConnect();
//消息

} 数据库 C# 二次开发 --------------------编程问答-------------------- 在写数据库的地方，catch异常将异常信息show出来，或者加入日志功能，写文本文件。 --------------------编程问答-------------------- #1，我也想，也写了catch，不执行。 --------------------编程问答-------------------- 谁来help me --------------------编程问答-------------------- 如果什么方法都不管用，最直接的方法就是在客户机上安装vs，调试模式下将错误重现。这事情我曾干过。
--------------------编程问答--------------------
安装了，无用。

有谁做过类似的开发，获取手机的来电显示的，联系本人，
补充：.NET技术 , C#
