在c＃中将数据集元素转换为字符串数组

Question

I am trying to convert the dataset item into the string and save into the array. But it gives me syntax error. Please help me out. This in VS 2005 and C#

Thanks in advance!!

string strdetailID[] = new string[4];
for(int i = 0; i < x ; i++)
{
   strdetailID[i] = dsImages.Tables[0].Rows[i]["Ad_detailsID"].ToString();
}

Answer 1

List<string> strDetailIDList = new List<string>();    

foreach(DataRow row in dsImages.Tables[0].Rows)
{
    strDetailIDList.Add(row["Ad_detailsID"].ToString());
}

string strDetailID[] = strDetailIDList.ToArray();

I have used a List<string> instead of a string array, as I think it would be easier to dynamically add elements, but if you want to still use a string array, you should get the general idea.

Answer 2

string[] strdetailID = new string[4];
for(int i = 0; i < x ; i++)
{
   strdetailID[i] = dsImages.Tables[0].Rows[i]["Ad_detailsID"].ToString();
}

This will work ..you made a mistake string strdetailID[]

Answer 3

It is possible to size array before for each loop and form array directly without list.

string [] strDetailID = new string[dsImages.Tables[0].Rows.Count];   
int arryIndex = 0;
foreach(DataRow row in dsImages.Tables[0].Rows)
{
    strDetailID [arryIndex] = row["Ad_detailsID"].ToString());
    arryIndex++;

}
