IOException.ToString是C#的System.IO命名空间下中的一个方法, 小编为大家找了一些网络大拿们常见的代码示例，源码中的IOException.ToString() 已经帮大家高亮显示了，大家可以重点学习IOException.ToString() 方法的写法，从而快速掌握该方法的应用。

IOException.ToString的代码示例1 - GetCloneRoot()

    using System.IO;

        private string GetCloneRoot(out string fullEnlistmentRootPathParameter)
        {
            fullEnlistmentRootPathParameter = null;

            try
            {
                string repoName = this.RepositoryURL.Substring(this.RepositoryURL.LastIndexOf('/') + 1);
                fullEnlistmentRootPathParameter =
                    string.IsNullOrWhiteSpace(this.EnlistmentRootPathParameter)
                    ? Path.Combine(Environment.CurrentDirectory, repoName)
                    : this.EnlistmentRootPathParameter;

                fullEnlistmentRootPathParameter = Path.GetFullPath(fullEnlistmentRootPathParameter);

                string errorMessage;
                string enlistmentRootPath;
                if (!GVFSPlatform.Instance.FileSystem.TryGetNormalizedPath(fullEnlistmentRootPathParameter, out enlistmentRootPath, out errorMessage))
                {
                    this.ReportErrorAndExit("Unable to determine normalized path of clone root: " + errorMessage);
                    return null;
