以下是使用C#调用基于Solidity编写的图片处理智能合约的完整指南，假设合约已使用MVS（Metaverse Smart Contract）标准实现：
1. 智能合约准备（示例合约）
solidity

pragma solidity ^0.8.0;contract ImageProcessor {struct ImageRecord {string ipfsHash;address owner;uint256 timestamp;bytes32 imageHash;}mapping(bytes32 => ImageRecord) private _records;event ImageRegistered(bytes32 indexed imageHash,address indexed owner,string ipfsHash);// 注册图片元数据（需配合链下存储如IPFS）function registerImage(string memory ipfsHash, bytes32 imageHash) external {require(_records[imageHash].owner == address(0), "Image already exists");_records[imageHash] = ImageRecord({ipfsHash: ipfsHash,owner: msg.sender,timestamp: block.timestamp,i
