尝试从comboBox中检索值时出现int cast错误 [英] int casting error when trying to retrieve value from comboBox

问题描述

我似乎无法找到一种方法将我的comboBox中的值转换为整数。我已经尝试了下面的
：

short iProjectID = Convert.ToInt16（cboProjects.SelectedValue）;


i继续获取a不允许钉装铸造错误。我怎么能这样做？

i can''t seem to find a way to cast the value in my comboBox to integer. i''ve
tried the following:
short iProjectID = Convert.ToInt16(cboProjects.SelectedValue);

i keep getting a "Sepcified cast is not allowed" error. how can i do this?

推荐答案

>短的iProjectID = Convert.ToInt16（cboProjects .SelectedValue）;


如果组合框包含字符串，请尝试


短iProjectID = Convert.ToInt16（（string）cboProjects.SelectedValue）;

>short iProjectID = Convert.ToInt16(cboProjects.SelectedValue);

If the combobox contains strings, try

short iProjectID = Convert.ToInt16((string)cboProjects.SelectedValue) ;
