在我的项目中,我使用visual studio 2010,crystal report 2010和Crystal.Reports.2010.Support.Pack.v13.0.5.当我运行代码并调用crystal report viewer时.我的Windows应用程序中发生此错误.我怎样才能在c#win App中解决这个错误？

错误:

无法加载文件或程序集'file:/// C:\ Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet1\crdb_adoplus.dll'或其依赖项之一.该系统找不到指定的文件.

这是sql to combobox中的retrive两个字段的函数: 代码:

public void FillCmbKala()
    {
        cmbKala.Items.Clear();
        objCon.Connecting();
        string SQL = "SELECT [kID],[kName] FROM tblKala ORDER BY kName";
        DataSet ds = new DataSet();
        using (SqlConnection cn = new SqlConnection(objCon.StrCon))
        {
              using (SqlDataAdapter adapter = new SqlDataAdapter(SQL, cn))
              {

                  cn.Open();

              try
              {
                  adapter.Fill(ds);
              }
              catch (SqlException e)
              {

                  MessageBox.Show("There was an error accessing your data of 'Kala'. DETAIL: " + e.ToString());
              }
              finally
              {
                 cn.Close();
              }
          }
     }
     cmbKala.DataSource = ds.Tables[0];
     cmbKala.DisplayMember = "kName";
     cmbKala.ValueMember = "kID";
}

当我使用组合框返回System.Data.DataRowView! …
