如何检查文件是否存在于unity android中? [英] How to check a file exist or not in unity android?

问题描述

我想在已知路径中找到文件，如果它已在android中预先存在，则用它触发一个事件(启用/禁用画布).这是我使用的示例-

I want to find the file in the path known and if it is pre-existing in android then trigger an event(enable/disable canvas) with it. Here is an example I used -

public void FileChk(){

    string filePath = "file://" + Application.temporaryCachePath + "/" + "folder23" + "/" + fileName;

    if (!fileName.Exists)
    {
        //event
    }   
    else
    {       
        //event     
    }
}

我在这里做错什么，以及当文件存在时如何触发此事件.

what am I doing wrong here and how do I get this event to trigger when the file exists.

推荐答案

您可以使用System.IO命名空间.

public void FileChk()
{
    string filePath = "file://" + Application.temporaryCachePath + "/" + "folder23" + "/" + fileName;

    if (System.IO.File.Exists(filePath))
    {
        // The file exists -> run event
    }
    else
    {
        // The file does not exist -> run event
    }
}

方法bool System.IO.File.Exists(string fileName)返回一个值，该值指示文件是否存在.

The method bool System.IO.File.Exists(string fileName) returns a value indicating if the file exists or not.
