有时候我们会需要让用户自己导入一个视频或图片到untiy，此时需要使用windows自己的资源浏览器
直接调用这个脚本的OpenResManager方法即可，返回值为选中的文件的绝对路径
public class LoadResourceByFileDlg : IUtility
{
[DllImport("user32.dll")]
private static extern IntPtr GetForegroundWindow(); //用于将一个窗口置顶
[DllImport("Comdlg32.dll", SetLastError = true, ThrowOnUnmappableChar = true, CharSet = CharSet.Auto)]
private static extern bool GetOpenFileName([In, Out] DialogConfig dialog); //这个方法名称必须为GetOpenFileName 用于打开读取文件窗口
[DllImport("Comdlg32.dll", SetLastError = true, ThrowOnUnmappableChar = true, CharSet = CharSet.Auto)]
private static extern bool GetSaveFileName([In, Out] DialogConfig dialog); //这个方法名称必须为GetSaveFileName 用于打开保存文件窗口
//这个类的作用是为打开文件浏览器的外部方法GetOpenFileName提供一个配置参数，类名可以自定义，但是属性必须是固定的
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)] //StructLayout允许我们自己定义属性在内存中顺序 Sequential为按顺序排列
public class DialogConfig
{
#region Config Field
public int structSize = 0;//设置窗口大小
public IntPtr dlgOwner = IntPtr.Zero;
public IntPtr instance = IntPtr.Zero;
public String filter = null;//文件类型
public String customFilter = null;
public int maxCustFilter = 0;
public int filterIndex = 0;
public String file = null;
public int maxFile = 0;
public String fileTitle = null;
public int maxFileTitle = 0;
public String initialDir = null;//指定路劲
public String title = null;//窗口名称
public int flags = 0;
public short fileOffset = 0;
public short fileExtension = 0;
public String defExt = null;
public IntPtr custData = IntPtr.Zero;
public IntPtr hook = IntPtr.Zero;

public string OpenResManager()
{
DialogConfig ofn = new DialogConfig();
ofn.structSize = Marshal.SizeOf(ofn);
//这里设置文件类型。可以指定视频，图片等其他文件。*.*默认为所有文件
//ofn.filter = "文件(*.mp4; *.mp4)\0 *.mp4; *.mp4";

ofn.dlgOwner = GetForegroundWindow(); //这一步将文件选择窗口置顶。
if (!GetOpenFileName(ofn))
{
return null;
}
return ofn.file;
}
}
另附将通过上述脚本获取到视频名后，拷贝到本地方法
private void OnImportVideo(string fullName)//导入视频
{
Debug.Log("文件名" + fullName);
if (string.IsNullOrEmpty(fullName))
{
return;
}
string extension = Path.GetExtension(fullName);
if (!(extension == ".mp4" || extension == ".avi" || extension == ".wmv"))
{
Debug.log("仅支持 .mp4 .avi .wmv 视频格式"));
return;
}
string fileNme = Path.GetFileName(fullName);//获取文件名
//复制文件
File.Copy(fullName, sceneTrainingModel.videoFolerPath + "/" + fileNme);
}
