我使用 C# 和 sql server compact 3.5 开发了一个桌面应用程序
我已经导入了所有必要的 dll
- System.Data.SqlServerCe.dll
- sqlceca35.dll
- sqlcecompact35.dll
- sqlceer35EN.dll
- sqlceme35.dll
- sqlceoledb35.dll
- sqlceqp35.dll
- sqlcese35.dll
当我在客户端机器上安装安装程序时，它在这台 PC 上运行且没有任何错误时部署它，它将在 database.sdf 中准确插入，并检索数据以自动完成。
当我想从中检索数据以填充组合框或网格时，它将产生错误
attempted to read write protected memory.
this is often an indication that other memory is corrupt
注意：如果我将此设置安装在另一台装有 VS 2008 的电脑上，它将正常工作而不会出现任何错误。我必须在客户端电脑上安装一些东西吗？
我也尝试在 VS2008 中构建：
Tools->Options
Debugging->General
uncheck option "Suppress JIT optimization on module load"
但结果是一样的。
这是我用于从 db 存储和检索数据的类
class dataBase
{
private SqlCeDataAdapter ad;
private SqlCeCommand cmd;
private string StringdbFileName=("Data Source=" + System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\sp.sdf").Replace(@"file:\", "");
private SqlCeConnection coon;
public dataBase()
{
coon = new SqlCeConnection(StringdbFileName);
coon.Close();
}
public int ExecuteSQL(string Query)
{
try
{
coon.Open();
cmd = new SqlCeCommand();
cmd.Connection = this.coon;
cmd.CommandText = Query;
return cmd.ExecuteNonQuery();
}
catch (Exception ex)
{
throw ex;
}
finally
{
coon.Close();
}
}
public DataTable GetDataTable(string Query)
{
try
{
coon.Open();
DataTable dt = new DataTable();
cmd = new SqlCeCommand();
cmd.CommandText = Query;
ad = new SqlCeDataAdapter(Query,coon);
ad.Fill(dt);
return dt;
}
catch (Exception ex)
{
throw ex;
}
finally
{
coon.Close();
}
}
public void FillComboBox(string Query, string DisplayMember,string ValueMember, ComboBox cmb)
{
try
{
coon.Open();
DataTable dt = new DataTable();
cmd = new SqlCeCommand();
cmd.CommandText = Query;
ad = new SqlCeDataAdapter(Query, coon);
ad.Fill(dt);
cmb.DataSource = dt;
cmb.DisplayMember = DisplayMember;
cmb.ValueMember = ValueMember;
}
catch (Exception ex)
{
throw ex;
}
finally
{
coon.Close();
}
}
}
