Storing values into report variable in SSRS reporting

Question

我正在asp.net中制作一个报告，为此，我想将数据表中的数据存储到报告变量中，但是问题是我希望将第三行第二列数据转换为变量，我不知道该怎么做，请提供我有什么建议。

Answer 1

The DataRow has also an indexer :

Object cellValue = dt.Rows[3][2];

But i would prefer the strongly typed Field extension method which also supports nullable types:

int number = dt.Rows[3].Field<int>(2);

or even more readable and less error-prone with the name of the column:

double otherNumber = dt.Rows[3].Field<double>("SecondColumnName");
