Unity 如何获取Texture 的内存大小

在Unity中，要获取Texture的内存文件大小，可以使用UnityEditor.TextureUtil类中的一些函数。这些函数提供了获取存储内存大小和运行时内存大小的方法。由于UnityEditor.TextureUtil是一个内部类，我们需要使用反射来访问它。

步骤

导入UnityEditor命名空间和System.Reflection命名空间：

using UnityEditor;
using System.Reflection;

创建一个函数来获取Texture的内存文件大小：

public static long GetTextureFileSize(Texture2D texture)
{long fileSize = 0;// 使用反射获取UnityEditor.TextureUtil类的TypeType textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");// 使用反射获取UnityEditor.TextureUtil类的GetStorageMemorySizeLong方法MethodInfo getStorageMemorySizeLongMethod = textureUtilType.GetMethod("GetStorageMemorySizeLong", BindingFlags.Static | BindingFlags.Public);// 调用GetStorageMemorySizeLong方法获取存储内存大小fileSize = (long)getStorageMemorySizeLongMethod.Invoke(null, new object[] { texture });return fileSize;
}

创建一个函数来获取Texture的运行时内存大小：

public static long GetTextureRuntimeMemorySize(Texture2D texture)
{long memorySize = 0;// 使用反射获取UnityEditor.TextureUtil类的TypeType textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");// 使用反射获取UnityEditor.TextureUtil类的GetRuntimeMemorySizeLong方法MethodInfo getRuntimeMemorySizeLongMethod = textureUtilType.GetMethod("GetRuntimeMemorySizeLong", BindingFlags.Static | BindingFlags.Public);// 调用GetRuntimeMemorySizeLong方法获取运行时内存大小memorySize = (long)getRuntimeMemorySizeLongMethod.Invoke(null, new object[] { texture });return memorySize;
}

示例代码

示例 1：获取Texture的存储内存大小

using UnityEngine;
using UnityEditor;
using System.Reflection;public class TextureSizeExample : MonoBehaviour
{[SerializeField]private Texture2D texture;private void Start(){long fileSize = GetTextureFileSize(texture);Debug.Log("Texture File Size: " + fileSize + " bytes");}private static long GetTextureFileSize(Texture2D texture){long fileSize = 0;Type textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");MethodInfo getStorageMemorySizeLongMethod = textureUtilType.GetMethod("GetStorageMemorySizeLong", BindingFlags.Static | BindingFlags.Public);fileSize = (long)getStorageMemorySizeLongMethod.Invoke(null, new object[] { texture });return fileSize;}
}

示例 2：获取Texture的运行时内存大小

using UnityEngine;
using UnityEditor;
using System.Reflection;public class TextureSizeExample : MonoBehaviour
{[SerializeField]private Texture2D texture;private void Start(){long memorySize = GetTextureRuntimeMemorySize(texture);Debug.Log("Texture Runtime Memory Size: " + memorySize + " bytes");}private static long GetTextureRuntimeMemorySize(Texture2D texture){long memorySize = 0;Type textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");MethodInfo getRuntimeMemorySizeLongMethod = textureUtilType.GetMethod("GetRuntimeMemorySizeLong", BindingFlags.Static | BindingFlags.Public);memorySize = (long)getRuntimeMemorySizeLongMethod.Invoke(null, new object[] { texture });return memorySize;}
}

示例 3：同时获取Texture的存储内存大小和运行时内存大小

using UnityEngine;
using UnityEditor;
using System.Reflection;public class TextureSizeExample : MonoBehaviour
{[SerializeField]private Texture2D texture;private void Start(){long fileSize = GetTextureFileSize(texture);long memorySize = GetTextureRuntimeMemorySize(texture);Debug.Log("Texture File Size: " + fileSize + " bytes");Debug.Log("Texture Runtime Memory Size: " + memorySize + " bytes");}private static long GetTextureFileSize(Texture2D texture){long fileSize = 0;Type textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");MethodInfo getStorageMemorySizeLongMethod = textureUtilType.GetMethod("GetStorageMemorySizeLong", BindingFlags.Static | BindingFlags.Public);fileSize = (long)getStorageMemorySizeLongMethod.Invoke(null, new object[] { texture });return fileSize;}private static long GetTextureRuntimeMemorySize(Texture2D texture){long memorySize = 0;Type textureUtilType = typeof(TextureImporter).Assembly.GetType("UnityEditor.TextureUtil");MethodInfo getRuntimeMemorySizeLongMethod = textureUtilType.GetMethod("GetRuntimeMemorySizeLong", BindingFlags.Static | BindingFlags.Public);memorySize = (long)getRuntimeMemorySizeLongMethod.Invoke(null, new object[] { texture });return memorySize;}
