[急求解答]``DataTable数据填充的问题!,,,大虾看官进来看看.....
--------------------编程问答--------------------
string[] arrs={};//你的20个数
DataTable dt = new DataTable("dt");
dt.Columns.Add("Nums", System.Type.GetType("System.String"));
string temp=string.empty;
for(int i=0;i<arrs.length;i++)
{
temp+=arrs[i]+",";
if(i%5==0)
{DataRow dr = dt.NewRow();
dr["Nums"] = temp.Substring(0,temp.Length-1);
dt.Rows.Add(dr);
}
}
手写，仅供参考 --------------------编程问答--------------------
--------------------编程问答--------------------
string[] arraystr = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20}
DataTable dt = new DataTable();
dt.Columns.Add("列名",typeof(string));
string temp = string.Empty;
for(int i=0;i<20;i++)
{
if(i%5==0)
{
DataRow dr = dt.NewRow();
dr[0] = temp.SubString(0,temp.LastIndex(","));
dt.Rows.Add(dr);
temp = string.Empty;
}
else
{
temp += arraystr[i] + ",";
}
}呵呵，写完才发现与一楼如此类似 --------------------编程问答-------------------- string[] arrs={};//你的20个数 DataTable dt = new DataTable("dt"); dt.Columns.Add("Nums", System.Type.GetType("System.String")); string temp=string.empty; for(int i=0;i<arrs.length;i++) { temp+=arrs[i]+","; if(i%5==0) {DataRow dr = dt.NewRow(); dr["Nums"] = temp.Substring(0,temp.Length-1); dt.Rows.Add(dr); } }
