利用c#书写调用MVS书写的图片处理文件.sol
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
// SPDX-License-Identifier: MIT 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
