Asp.net 根据API响应填充GridView列数据

我是ASP.NET新手。我想根据API的响应动态地向

GridView

添加一列

id      User     secretcode
1       u1       {response from the API based on the Id value}
2       u1       {response from the API based on the Id value}
3       u1       {response from the API based on the Id value}
4       u1       {response from the API based on the Id value}
5       u1       {response from the API based on the Id value}

id

和

User

已经在我的数据库表（users）中，因此对于每个返回的行，我想调用API来填充我的第三列，即

secretcode

。基本上，我不知道在哪里使用ForEach循环

这是我正在研究的粗略代码：

DataTable table = new DataTable();
DataColumn col3 = new DataColumn("Secretcode");
col3.DataType = System.Type.GetType("System.Int");
table.Columns.Add(col3);
row[col3] = {response data from API}
gvTest.DataSource = table;
gvTest.DataBind();

---

也许是这样的

DataTable table = new DataTable();
DataColumn col = new DataColumn("Secretcode");
table.Columns.Add(col);
for(int i = 0; i < table.Rows.Count; i++)
{
    // Where 'SomeAPICall()' is calling the API and returning the
    // correct data type. If it is returning an object you may want
    // to convert it before you attach it to the table

    table.Rows[i]["Secretcode"] = SomeAPICall(table.Rows[i]["id"]);
}
gvTest.DataSource = table;
gvTest.DataBind();

我通常更喜欢使用for循环，因为通常您希望在两个不同的集合上使用相同的索引号，而这在foreach循环中是无法实现的。在这种情况下，这并不重要

DataTable table = new DataTable();
DataColumn col = new DataColumn("Secretcode");
table.Columns.Add(col);
foreach(DataRow row in table.Rows)
{
    // Where 'SomeAPICall()' is calling the API and returning the
    // correct data type. If it is returning an object you may want
    // to convert it before you attach it to the table

    row["Secretcode"] = SomeAPICall(row["id"]);
}
gvTest.DataSource = table;
gvTest.DataBind();
