什么叫案件卷宗管理系统?理解其概念、重要性与主要内容

// 案件卷宗实体类定义
public class CaseFile
{
    public int Id { get; set; }
    public string CaseNumber { get; set; }
    public string CaseName { get; set; }
    public DateTime CreateTime { get; set; }
    public string CreatedBy { get; set; }
    public FileStatus Status { get; set; }
    public ICollection Documents { get; set; }
}

// 文档实体类
public class Document
{
    public int Id { get; set; }
    public string FileName { get; set; }
    public string FilePath { get; set; }
    public long FileSize { get; set; }
    public DateTime UploadTime { get; set; }
    public int CaseFileId { get; set; }
    public CaseFile CaseFile { get; set; }
}

// 卷宗检索功能实现
class CaseFileSearch {
  constructor() {
    this.searchCriteria = {
      caseNumber: '',
      caseName: '',
      startDate: null,
      endDate: null,
      status: 'all'
    };
  }

  // 执行检索
  async executeSearch() {
    try {
      const response = await fetch('/api/casefiles/search', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify(this.searchCriteria)
      });
      
      const results = await response.json();
      this.displayResults(results);
    } catch (error) {
      console.error('检索失败:', error);
    }
  }

  // 显示检索结果
  displayResults(results) {
    const resultsContainer = document.getElementById('search-results');
    resultsContainer.innerHTML = results.map(result => 
      `<div class="result-item">
        <h4>${result.caseName}</h4>
        <p>案号: ${result.caseNumber}</p>
        <p>创建时间: ${new Date(result.createTime).toLocaleDateString()}</p>
      </div>`
    ).join('');
  }
}
