OdbcDataReader.GetInt16(Int32) 方法

定义

作为 16 位有符号整数获取指定列的值。Gets the value of the specified column as a 16-bit signed integer.

public:
 virtual short GetInt16(int i);
public short GetInt16 (int i);
abstract member GetInt16 : int -> int16
override this.GetInt16 : int -> int16
Public Function GetInt16 (i As Integer) As Short

参数

i
Int32

从零开始的列序号。The zero-based column ordinal.

返回

指定列的 16 位有符号整数形式的值。The value of the specified column as a 16-bit signed integer.

实现

异常

指定的强制转换无效。The specified cast is not valid.

注解

基于 ODBC 驱动程序的基础功能执行转换。Conversions are performed based on the underlying capabilities of the ODBC driver. 如果不支持转换,则方法调用将失败。If the conversion is not supported, the method call fails.

调用 IsDBNull 在调用此方法之前查找 null 值。Call IsDBNull to look for null values before calling this method.
