如何将符号“？”转换为在 c# 中到 vb.net 中？
我正在尝试将 c# 代码转换为 vb.net，但在转换符号“？”时遇到困难从 C# 到 vb.net。这是我要转换的代码
public audit_trail Mapper(IDataReader rdr)
{
audit_trail audit_trail = new audit_trail();
audit_trail.Log_id = rdr["Log_id"] is DBNull ? 0 : (int)rdr["Log_id"];
audit_trail.Host = rdr["Host"] is DBNull ? string.Empty : (string)rdr["Host"];
return audit_trail;
}
如何转换符号“？”到vb.net？
我想转换
audit_trail.Host = rdr["Host"] is DBNull ? string.Empty : (string)rdr["Host"];
成类似的东西
if rdr["Host"] is DBNull.Value then
audit_trail.Host = string.Empty
else
audit_trail.Host = rdr["Host"]
end if
，但代码太长，代码行太多..你们有想法转换成短的吗？

I would like to convert

to something like
if rdr["Host"] is DBNull.Value then
audit_trail.Host = string.Empty

三元运算符的 Visual Basic 语法为
If([condition,] op1, op2)。The visual basic syntax for the ternary operator is
If([condition,] op1, op2).
