如何将arraylist变量传递给c＃中的函数 [英] How to pass the arraylist variable to the function in c#

问题描述

我是c＃的新手，我想将Arraylist变量传递给CompareArrayList函数，但是错误是输入字符串格式不正确，任何人都可以告诉我，如何将arraylist变量传递给函数在c＃中，我的代码在下面

Hi,I am new to c# ,I want to pass the Arraylist variable to the function CompareArrayList,But error is that 'input string is not in correct format' ,Can anyone tell me ,how to pass the arraylist variable to the function in c#, my code is below

protected void RelativeFamilyIDFrom(Double RelativeMemberID)
{
        sSQL = "SELECT AF_FamilyID FROM AllFamily_Master";
        sSQL = sSQL + " WHERE AF_MemberID IN('" + RelativeMemberID + "')";

        DS = new DataSet();
        da = new OdbcDataAdapter(sSQL,conn);
        da.Fill(DS);

        ArrayList list = new ArrayList();
        if (DS.Tables.Count > 0)
        {
            if (DS.Tables["table"].Rows.Count > 0)
            {
                for (int i = 0; i < DS.Tables["table"].Rows.Count; i++)
                {
                    allFamily[i] = Convert.ToDouble( DS.Tables["table"].Rows[i]["AF_FamilyID"].ToString());

                    list.Add(Convert.ToDouble(DS.Tables["table"].Rows[i]["AF_FamilyID"].ToString()));

                }
                CompareArrayList(list, Convert.ToDouble(lblUserToFamilyID.ToString()));
            }
        }
}

private bool CompareArrayList(ArrayList RelativeFamilyID,Double arr2)
{
        for (int i = 0; i < RelativeFamilyID.Count; i++)
        {
            if (!arr2.Equals(RelativeFamilyID[i]))
            return false;

        }
          return true;
}

推荐答案

看起来像将lblUserToFamilyID值转换为Double时发生错误。调试lblUserToFamilyID的值。



如果lblUserToFamilyID是一个控件，那么使用lblUserToFamilyID.Text.ToString（）

It look likes error occured while converting lblUserToFamilyID value to Double. Debug the value of lblUserToFamilyID.

if lblUserToFamilyID is a control then use lblUserToFamilyID.Text.ToString()
