[Unity]字符串判断为空物体解决

 

 

...
private Data data_ = new Data();
...
if(data_.str != "")
{
...
}
...

public class Data
{
name = "";
}

 

...
private Data data_ = new Data();
...
if(data_.str != null)
{
...
}
...

public class Data
{
name = "";
}

 

应该判断str.Length

...
private Data data_ = new Data();
...
if(data_.str.Length > 1)
{
...
}
...

public class Data
{
name = "";
}
